The sequence data from VM_2_30.06.-CMV-F and VM_3_30.06.-CMV-F arrived and showed as expected a homologous region with the ORFs of the corresponding VPs.<br>
+
-
 
+
-
The process of VPex1, VPex2 and VPex3 sequencing is nearly finished. For further progress the oligos that prime at different locations in the Rap/Cap ORFs are required.
+
-
The actual progress of the sequencing is shown in the image on the right side:
+
-
 
+
-
*For the sequencing of VPex1 and VPex2 one further read will be required to achieve a continuous contig.
+
-
*The sequencing of VPex3 is completed but contains two point mutations.
+
-
 
+
-
The investigation of the point mutations revealed that the:
+
-
*first mutation (TAC=>TAT) is silent and codes for Tyrosine. The original codon TAC has a codon usage of 58% in Homo sapiens and 25% in E. coli where as the new codon TAT has a codon usage of 42% in H. sapiens and 75% in E. coli. There for this mutation could be an optimisation of the sequence for an approach to express the VP in E.coli.
+
-
*second mutation (CCG=>CCA) is silent and codes for Proline. The original codon CCG has a codon usage of 11% in H. sapiens and 77% in E.coli weher as the new codon CCA has a codon usage of 27% in H. sapiens and 15%. This mutation would lead to an optimiced expression in human cells.
+
-
Therefor the combination of these two "optimized" codon does not make any sense in this combination.

total celldeath! <br>
+
-
Looks like we should not transduce 3x10^5 cells with 1000 µl (or more) of our viral solution because almost all cells died in all approaches and the medium indicator was yellow.
+
-
So we can not say if resuspendig the cells with the viral soultion is a useful alteration of the standart protocol.
+
<br>
<br>
-
<p style="font-size:12px; font-weight: bold; color: red;">@Chris and Patrick: The cells which has not been resuspended died aswell??  yes (Patrick) ... so u think the volume (1000µL) of the viral stock solution  is too high and cell death is not caused by the "rough" reuspension?  yes (Patrick)  ... Could u maybe upload some pictures even though it did not work, but to documentate it properly!! thx Bea ... No, already thrown away and we could not take good pictures because of very thick bunches of dead cells, results confirmed by Sven (Patrick)  </p> <br>

<p><b>Investigators: Patrick & Volker</b></p><br>

-
The 453 insertion site is acoording to [Boucas et al., 2009] a promising alternative to the 585/588 integration site.
+
-
The Peptides were integrated between the 453 Glycine and the 454 Threonine. This risidues were annotated in the gene maps (Genious) and visualized in the 3D structure (PyMOL).

+
-
 
+
-
The sequence of the major site for peptide integration into the capsid proteins was extracted from the viral sequence and pasted into the program [https://www.dna20.com/ DNA 2.0]. In an first atempt the 4 amino acids that form the loop (5' - RGNR - 3') were used with the two flanking amino acids from the wild type sequence on each side.
+
-
The goal of this theoretical investigation is to use alternative codons to insert restriction sites into the wild type loop to make later cloning easier.
+
-
This was repeated in an second atempt with five flanking amino acids but did not reveal additional useful restriction sites.
+
-
 
+
-
Informations for the restriction enzymes were looked up in the [http://www.neb.com/nebecomm/products/category1.asp?#2 NEB Product catalogue].

Summary:
+
-
The KpnI restriction site seems to be a good possibility to make the 453 insertion site ready for easy integration of peptides.<br>
+
-
Especially the position where the cut is performed is ideal for our purpose because peptides are usually integrated after the Glycine 453 as described for example in [Boucas et al.; 2009].

+
-
<p><b>Investigator: Volker</b></p>
+
-
 
+
-
The construct pAAV_RC that we have bougth from Stratagene will be a central part of our Virus construction kit and therefor it has to be cleared from restriction sites that are used in the iGEM-standard. <br>
+
-
There are five iGEM restriction sites in the pAAV-RC:<br>
+
-
*PstI at position (310)
+
-
*EcoRI at position (1578)
+
-
*PstI at position (1773)
+
-
*EcoRI at position (1796)
+
-
*PstI at position (4073)
+
-
 
+
-
The relative location to each other and other planed modifications in this sequence make it reasonable to replace the PstI (310) and PStI (4073) with site directed mutagenesis and to order a synthesis of the region with the three other restriction sites.<br>
+
-
 
+
-
The primers for the site directed mutagenesis were designed:<br>

-
The region with the three restriction sites that are located near to each other is show in the picture above. The restriction sites indicated in light blue are single cutters and can therefor be use to clone the synthesized fragment into the original sequence of pAAV-RC.<br>
+
-
For this purpose the restriction sites BstBI (1435) and SwaI (2004) will be used because they are availible in the lab stock and have 100% fidelity in one of the NEB buffers.<br>

This are all the restriction sites in the ORFs for the Rep and Cap proteins. In the backbone of the pAAV_RC there are more restriction sites in the iGEM standard. These restriction sites should not cause any problems when the insert in cloned into a standard iGEM vector.
+
-
An other interesting question is what has been changed in the regulatory region p5. This will be important to determine the sequence that is required for the functional expression of the pAAV-RC.

+
-
The sequence 5'-CTC CAG AGA GGC AAC AGA CAA -3' codes in the pAAV-RC construct for the amino acids LQRGNRQ.<br>

-
In order to achieve the recommanded mutation the sequence has to be changed to: 5'-CTC CAG GCT GGC AAC GCT CAA -3'<br> which codes for LQAGNAQ.<br>
+
-
 
+
-
The problem is that in this R585A R588A KO version there is no possible codon usage to encode a BstEII restriction site that would make it possible to integrate peptides in an easy fashion.<br>
+
-
An R585A R588L KO version would contain the BstEII restriction site and could be a possible alternative to the R585A R588A KO version.
+
-
 
+
-
Questions to adress on monday:
+
-
*Is the proposed R585A_R588L_KO mutation possible?
+
-
*Are iGEM standard vectors availible that do not contain KpnI and BstEII?

+
* delete EcoRI (2x) and PstI (2x)  
-
Hanna <br>
+
-
A new strategy for ITR BioBrick production was figured out. This method does NOT require any PCR steps! :) <br>
+
-
We want to take advantage of the fact, that the ITRs are flanked by NotI and PstI. <br>
+
-
"Short version" of the strategy: <br>
+
-
* Digestion of pAAV_MCS with AlwNI. Result: one large fragment (2982 bp) with right ITR; one small fragment (1674 bp) with left ITR.
+
-
* Separate fragments via gel run.
+
-
* Digest them with NotI and PstI.
+
-
* Präfix and suffix oligos were designed. They need to be hybridized and ligated to the left and right ITR with several intermediate steps (subcloning into pSB1C3 etc.). The oligos posess compatible overhangs to the PstI and NotI restriction sites of the ITR but do not generate new restriction sites after ligation!

+
* NotI and PstI (in sequence?) flank the ITRs: its the question if we can/must delete them?
-
Hanna <br>
+
* where exactly starts and ends the sequence (Patrick)? 
-
The beta-globin sequence (pAAV_MCS) contains no iGEM-restriction sites. Therefore we decided NOT to order the sequence, but to perform a PCR with RFC10 overhang primers: <br>
+
* it should be checked up if there is a possibility to use all of the three ITRs.
-
[[File:Freiburg10 beta-globin for.JPG|600px|]] <br>
+
* we blasted the ITR (left) of the MCS vektor (Stratagene). we got a 92% "Coverage" with the AAV2 genom (to 100%). from the  alignment (Stratagene ITR with ITR of the AAV2 genom) we got:<br>

+
[[File:Freiburg10 ITR(left)-Stratagene vs. ITR AAV2.jpg|500x500px|]]
 +
You can see, that the ITR sequence beginns 4 bp after the PstI restriction site. thereupon we did a secundary structure analyse (www.dinamelt.bioinfo.rpi.edu), with the following structurewe got: <br>
 +
[[Media:Freiburg10_AAV2ITR(left)nachBlast.pdf]] <br>
 +
conclusion: the big loop of the secondary structure dosent change if we delete the PstI restriction site (cf. with other uploadet secondary structures), it should be considered that we can't add random bp that could affect the secundary structure. <br>

We want to investigate which of the following approaches yields a better transduction efficiency.
+
-
*Half of the transfected cells were exposed 3 cycles of thawing and freezing and then centrifuged (15 ml falcon, 2100G). The supernatant was transfered into a new 15 ml falcon and used for transduction.
+
-
*The other half was centrifuged at 300 G for 5min . The supernatant was transfered into another 15 ml falcon and the pellet was resuspended with 5 ml of DMEM. The content of these two falcons was also exposed to 3 cycles of thawing and freezing and then used for transduction.
+
-
 
+
-
 
+
-
* We have got 2 10 cm cellculture dishes with 10µg and 2 dishes with 20µg DNA used for transfection.
+
-

-
Approach with standart protocol (one dish with 10 and the other with 20µg Plasmids)(2100 G and 3 cycles of freezing and thawing)
+
-
 
+
-
 
+
-
Deviations from the standart protocol:
+
-
* The cells were centrifuged at 2100 G instead of 10.000 G
+
-
* The viruses were harvested after 44 hours

====<p style= "font-weight: bold; color: blue;">Order oligos for GMK_TK30</p>====
+
We blasted the sequence of the β-globin and additional nukleotides „vorne und hintendran“.
-
Investigator: '''Bea'''<br />
+
We found only 70% coverage with the human β-globin-intron add. some parts of the exon 3.
-
Oligos have been ordered at sigmaaldrich in order to insert prefix and suffix to fusionenzyme mGMK_TK30 in RFC25.  
+
For this reason we think that the pAAV_MCS annotation of the β-Globin-intron of Stratagene is too generously.<br>
-
<br>
+
In addition the alignment of the human ß-globin showed that only parts of the intron 2 (5’) and exon 3 are integratet into the vector.
-
<br>
+
We assume that the informations from Stratagene are not total correctly ( intron flanket by the splicedonors and the acceptor-sequence).
-
[[File:Freiburg10 Cloning strategy for preparation of inserzting RFC25 to fusionenzyme gmk tk30 09 07 2010.jpg]]
+
We blasted the sequence between the CMV-promoter and the origin beginning of the ß-globin intron.
-
<br>
+
We found a 98,8% coverage with a synthetic CMV-promoterconstruct ( 1 nucleotide difference).
-
[[File:Freiburg10 Cloning strategy for preparation of inserzting RFC25 to fusionenzyme gmk tk30 09 07 2010 page2.jpg]]
+
Literature: „Diverse plasmid DNA vectors by directed  molecular evolution of cytomegalovirus promoters. (Wright A. et al.)“<br>
-
<br>
+
→The question arises if we can omit the ß-globin (because the exact function is unknown).
-
[[File:Freiburg10 Cloning strategy for preparation of inserzting RFC25 to fusionenzyme gmk tk30 09 07 2010 page3.jpg]]
+
For this we should contact various Companys (GeneArt, DNA2.0, Mr. Gene,…) to get more information.
-
<br>
+
In addition we could test the expression with and without ß-globin.

* agarose gel was performed with digested samples and revealed 3 distinct bands, while only 1-2 bands have been expected. Because of the density of the bands it might be that the digestion with DpnI did not work properly, thus additional 1 µl of DpnI was added to each sample. Incubation @ 37 C lasted 1 h.

<b>Conclusions </b>
+
-
* Higher amounts of Plasmids (24, 30µg) seems to have no obvious effect on YFP expression
+
-
* Theres no difference in YFP expression comparing resuspended samples to not resuspended samples
+
-
* The amount of dead HT cells is about 25%, it is not clear if it is either AAV induced or mechanic stress (Trypsin, washing procedure)
+
-
+
-
Next steps:
+
-
 
+
-
* does the amount of GOI (ng plasmids) has an effect on YFP expression 
+
-
* compare transduced to non transduced cells (vitality), or in other words is the mechanic stress responsible for 25% dead cell ratio?
+
-
* comparison of transduction efficiency of different virus stock production routines
+

Unfortunately it turned out, that the digestion step of the 1st try didn't work: After the transformation very much colonies grew on the plates. Sequencing delivered, that survival of the bacteria was due to re-ligated vector... Therefore the whole experiment will be performed again today.

'''Comments''': While cloning theoretically the hGH PCR product into the vector pSB1C3, it was recognized that the primers that were used for PCR for

*hGH RFC10 production and

do not contain the required "G" at the end of the prefix  and the "T" in the suffix add-on in the RFC10 standard. They were already used by performing a PCR with the add-on prefix and suffix primer, but we did not clone it into the pSB1C3 because of the wrong add-on tails. Therefore new primers were designed and ordered.

Bacteria also grew on control plates. Control means: Ligation of digested vector (pGA14_Cerulean) without insert (Präfix and left ITR). Therefore it seemed that somehow pGA14 religated (Can't be if vector digested completely). Therefore 10 colonies were picked, in order to increase the chance to get a successfully ligated plasmid.

Gelrun (1% Agarose), 55 minutes, 115 mV: Results: See picture. Interpretation of the results: ? The "upper" DNA seems to be undigested vector underneath the probably digested vector with an estimated size of about 5600 bp. The mutual insert (mgmk_tk30) should be about 1700 bp. There are probably several DNA coil structures visible but not our mutual insert. To do : ligate again.

Because there was one positive non-template control (H2O) yesterday, we performed the qPCR one more time.<br>
+
-
For this purpose we also calculated the plasmid pipetting for the standard curve again:
+
-
* c(P9) = 272 ng/µL --> 3 x 1:10 = 1:1000 dilution.
+
-
* 2.68 µL of the 1:1000 dilution was added to 52.32 µL H2O = 2600000 copies/µL.
+
-
* By performing 1:10 dilutions further 6 "standard samples" were created: 260000 copies/µL; 26000 copies/µL; 2600 copies/µL; 260 copies/µL, 26 copies/µL, 2.6 copies/µL

<br>

+
-
<br>
+
-
<br>
+
-
Sequencing delivered, that the präfixes were fused successfully to the ITRs. The mismatch (orange box) was due to the alignment with the RFC10 präfix... (oligos were ordered!), what means, that the sequencing is OK.<br>
+
-
Interestingly it seems, that not only we had problems with PCR of the ITR -> Very strong secondary structures. Even sequencing of the ITRs seems impossible under normal conditions: Exactly at the point where the ITR sequence starts the sequencing signal delivered no clear results. <br>

<b>Theoretical cloning:</b> (Volker, Hanna)
 +
* The CMV promoter (mainly the regulatory region) was further characterized: For this purpose U.S. patent no. 5,385,839 was used. [[Media:Freiburg10_Patent_US5385839A.pdf]]
 +
* Further on the CMV promoter sequence was blasted. The results delivered a 98% query coverage with the "Human herpesvirus 5 strain Toledo, complete genome" (accession no.: GU937742.1). Interestingly the maximal identity was just 99%. This can be explained due to a nucleotide deletion and a C-T transition (red circles), which were also marked in Geneious.

'''LB medium''' was prepared: (Patrick and Chris W.)
 +
* 10 g Bacto-Tryptone, 5 g Bacto-Yeast, 10 g NaCl were mixed in 500 mL milipore-H2O.
 +
* Volume was adjusted to 1 L with milipore-H2O.
 +
* 100 mL flasks were each filled with 50 mL medium.
 +
* 0.75 g agar was added to each flask.
 +
* LB was sterilized by autoclaving and is now stored at room temperature.

The inoculated agar plates from 'Cloning together of pAAV_RC PstI 310 and 4073 with two enzymes' were checked for colonies. Three clones were picked and in each case inoculated 20 ml DYT + Amp at 10:20.

Mini prep of two pAAV_RC_SDM_PstI_310_4073. Results: It was checked visually whether enough E. coli BL21 cells had grown. Therefore only two midi preps were carried out, according to the standard protocol (Final elution with 50 µl). Unfortunately both of them yielded a quite low plasmid concentration, probably due to the short growth time (7 h). <br>

'''Summary''': Four site-directed mutagenesis have been performed with the plasmid pAAV_RC_PstI_310+4073 (pAAV_RC_1.1) = P87.
+
-
*Site-directed mutagenesis in order to delete restriction site BamHI
+
-
**with shorter elongation time (modified protocol)
+
-
**with longer elongation time
+
-
*Site-directed mutagenesis in order to delete restriction site SalI
+
-
**with shorter elongation time (modified protocol)
+
-
**with longer elongation time
+
-
*The samples  were digested with 0,5µL DpnI after site-directed mutagenesis were performed in order to remove bacterial DNA template.
+
-
*Trafos have been performed with all four samples. Trafo plates are containing ampicillin.

<p><b>Investigators: Bea, Adrian, Hanna, Sven</b></p>
-
<p style="font-size:13px; color:#Fuchsia;">'''Comments:''' Cloning approach was continued: RFC10-Präfix_rightITR was ligated to RFC10-Suffix and pGA14 and leftITR was ligated to RFC10-Präfix and pGA14 over night. Trafo of these samples was performed in order to pick clones tomorrow.  </p>
+
-
<br>
+
-
Trafo was performed following the standard protocol. Abberance: 4 µL DNA was added to BL21 cells. <br>
+
-
<br>
+
<br>
<br>
 +
In order to replace the multiple cloning site of the pAAV_MCS vector from Stratagene by RFC25, two oligos were designed. After their hybridization the overhangs correspond to ClaI- and BglII restriction sites. A digestion with BglII and ClaI will be performed with pAAV-MCS and then will be ligated with the designed oligos.<br>
 +
The oligos (see link) were ordered at Sigma-Aldrich. Estimated shipment: 31.05.2010 .<br>

Marker did not resolute very good. Expected sizes of PCR products:
+
-
*hGH = 510 bp
+
-
*beta globin intron: 524 bp
+
-
It can be seen (or estimated) that two intensive bands are visible at around 500 bp. Therefore these two bands were cut out and a gel extraction was performed. The lower visible band at around 100 bp of hGH is an additional band generated at the pCR reaction. The two intensive blurred bands belong to the loading dye added to the samples.

The vector was digested with XbaI and PstI. Expected sizes have been:
+
-
*pSB1C3 = 2072bp
+
-
*CFP: 732bp
+
-
It can be seen that the vector pSB1C3_RFC25_CFP was digested and two visible bands can be seen on the gel. The lower band corresponds to the CFP fragment (~700 - 800 bp), the higher band corresponds to the plasmid backbone at around 2000-3000 bp. The higher band was cut out and extracted by gel extraction.

Abberances: <br>
+
Cloning did not work (see lab day 25.05.2010) either with NotI or with NotI-HF. Gel did not show any proper band at the expected size. <br>
-
* 3µL DNA-sample was added to 50 µL cells (BL21).
+
There will be used EtBr instead of gelred in the agarose gel and the incubation time of digestion will be prolonged. Further details are followed. <br>
-
* Cells were incubated on ice for just 10 minutes.
+
NOTE: There are three restriction sites of NotI in the pCMV-mVenus_YFP. If cloning with NotI, the polyA hGH signal will be deleted. therefore cloning with NotI is '''not''' possible .
-
* Heat shock: 42 seconds at 42°C.
+
-
* Incubation for just 35 minutes at 37°C, rotating (800 rpm).
+
-
* Agar plates were prepared with Lab-Ampicillin.

'''2. Control:''' Bacteria were taken from the right-ITR-lawn an resuspended in 100 µL DYT. They were plated on "LabAmp-plates" and stored at 37°C. <br>
 
-
-> If something is wrong with our Ampicillin the non-transformed bacteria have progeny-advantages and will crowd out the transformed cells. This means: If there will be no colonies detectable on the new plates, something is wrong with our Ampicillin! <br>

''' 3. Picking clones of the left ITR plate:''' Two large and two small clones were picked from the left ITR plate and each was resuspened in 50 µL DYT. An "LabAmp-plate" was quartered and the four resuspened colonies were individualized each on one quarte of the plate. <br>

'''Investigator: Hanna''' <br>

-
In order to target the EGF-receptor (EGFR/ErbB-1/Her1) an affibody molecule can be fused to the N-terminus of e.g. VP2, which is expressed in trans. The ZEGFR:1907 was chosen for this approach. Because just the amino acid sequence is published by Friedman et al., 2008, the sequence was translated with Mr. Gene's help :) and optimized for mammalian expression. <br>

'''Strategy:'''

Results: Test digestion of pCMV_MCS with NotI delivered plausibel results (expected fragment size: ~ 27 kbp and 17 kbp).
 +
Unfortunately the digestion of pCMV_mVenus_YFP with PstI and MluI resulted in one 2.9 kbp and one 1.2 kbp fragment, which didn't correspond to the expected fragment sizes of 19 kbp and 33 kbp - but to fragment sizes of pCMV_MCS without mVenus_YFP!

The competent E.coli XL-1-blue and competent E.coli BL21 which were prepared the day before were test-transformed with pUC18 - following the standard protocol. Cells were plated on agar plates containing ampicillin and stored over night at 37°C.

'''Conclusion:''' The PCR amplification with designed primers to insert prefix and suffix in RFC25 standard can be verified. No nucleotide transitions can be detected. The prefix and suffix are in the designed standards. Additionally it can be confirmed that the mGMK was inserted successfully into the pAAV_RFC25 plasmid and do NOT contain any iGEM restriction sites When receiving the ordered tk30 from Mr.Gene it can be fused to the mGMK and will the be ready for using and sending to the IGEM registry (maybe this needed to be cloned into pSB1C3).

No bands can be detected at the expected sizes. The fragment size seems to be inbetween the expectation of either 150 and 750 bp. Further on there is also an additional band visible. Because of that it's not possible to say, whether cloning worked. Therefore the three clones marked in the picture were sent to GATC for sequencing: <br>

TAE buffer was changed before start, the samples have been diluted to 1/3 but the bands are still very distinct. However, it is possible to analyse the gel. Rep 68 contains no PstI restriction sites anymore, while Rep 78 shows one band, which might be due to the additional PstI restiction site.

GATC didn't manage to do the sequencing of the left ITR-Präfix construct until now. This can be interpreted as positive news, because this increases the fact that the ITR is in the plasmid (very strong secondary structures!). Therefore cloning will  be continued today:

In order to alter the tropism of AAV2 several modifications have to be performed.

'''Investigator: Hanna''' <br>

First of all the binding to Heparan Sulfate Proteoglycan has to be disrupted. This can be done by R585A and R588A transistions:
-
<br>
+
[[File:Freiburg10 R585A R588A.jpg|800px|]]
-
Sequencing results delivered that the right ITR was succesfully ligated to the pGA14 plasmid. Unfortunately just about 100 bp were successfully sequenced. Within the ITR region sequencing seemed one more time not to be possible due to the very strong secondary structures which hinder the polymerase to read through. Therefore we can just validate that the ITR with the prefix is inside pGA14, but it's not possible to give a statement about the ITR quality or whether the suffix was successfully fused to the sequence. Theoretically the digested plasmid is not able to religate without ITR and Suffix sequence. But noone knows what our ''E.colis'' are able to achieve :)

Digestion of the right ITR fragment worked well. Unfortunately the left ITR fragment is too large. The ecpectation was ~ 151 bp. It seemed to consist of ~ 300 bp. --> Two ITRs in tandem??? Hopefully GATC will find a way in order to sequence the ITRs!

Theoretical cloning

Investigators: Adrian, Hanna, Bea, Patrick, Chris W.



There are several matters to do in theoretical cloning. The modularization/modification of the stratagene plasmids and the enzymes. :

1. Cap-Gen:

  • delete the PstI-restriction site
  • insert the antibody fragment (targeting): sequence? in which part of VP1? (Patrick)
  • add prefix & suffix
  • disable binding of Heparan Sulphat Proteoglycan


2. Rep-Gen:

  • delete EcoRI (2x) and PstI (2x)


3. ITRs:

  • NotI and PstI (in sequence?) flank the ITRs: its the question if we can/must delete them?
  • where exactly starts and ends the sequence (Patrick)?
  • it should be checked up if there is a possibility to use all of the three ITRs.
  • we blasted the ITR (left) of the MCS vektor (Stratagene). we got a 92% "Coverage" with the AAV2 genom (to 100%). from the alignment (Stratagene ITR with ITR of the AAV2 genom) we got:
Freiburg10 ITR(left)-Stratagene vs. ITR AAV2.jpg

You can see, that the ITR sequence beginns 4 bp after the PstI restriction site. thereupon we did a secundary structure analyse (www.dinamelt.bioinfo.rpi.edu), with the following structurewe got:
Media:Freiburg10_AAV2ITR(left)nachBlast.pdf
conclusion: the big loop of the secondary structure dosent change if we delete the PstI restriction site (cf. with other uploadet secondary structures), it should be considered that we can't add random bp that could affect the secundary structure.
To do: which bp, which sequence could/can be insertet? cf. the genome of AAV2

4. MCS:

  • replacement through the iGEM-MCS
  • where is the beginning and ending of the MCS in the Vector? ß-globin function and sequence (search for literature and patents, which are denoted in the AAV-Helper-Free-System Manual)
  • in this context it would be also important to find out where the beta-Globulin-Intron exactly starts or rather we can cut out the MCS.


5. enzymes:

  • Thymidinkinase: find informations. TK30 (Bea), SR39 (Hanna)
  • Cytosindeaminase: find informations (Adrian)


in addition we downloadet, addet and anotated the sequence of the pHelper plasmid of stratagene in Geneious (see "Constructs").


insert the antibody fragment (targeting): sequence? in which part of VP1? (Patrick)

Protocolls

Investigators: Anissa, Kerstin


  • adaption and extension of the standart prorcolls (Cloning for Pro's)
  • we startet to create a protokoll-mask for the praktical-cloning (short version for labwork)

8. Labday 10.05.2010

Stock solutions

Investigators: Adrian, Chris W., Chris L., Bea, Achim, Patrick, Hanna, (Sven)


The following stock solutions were prepared:
1. Antibiotics:

  • Ampicillin: 2 g Ampicillin were dissolved in 20 mL ethanol (70%), filled into 2 mL tubes and stored at -20°C.
  • Chloramphenicol: 0.5 g Chloramphenicol were dissolved in 20 mL ethanol (70%), filled into 2 mL tubes and stored at the -20°C.
  • Kanamycin: 1 g Kanamycin was dissolved in 20 mL multipore-H2O, sterilized by filtration and filled into 2 mL tubes and stored at the -20°C.
  • Tetracyclin: 0.5 g Tetracyclin were dissolved in 20 mL ethanol (70%) and filled into 2 mL tubes. The tubes were wrapped with aluminium foil (light sensitive!) and stored at -20°C.

2. ITPG solution (1 M):

  • ~ 4.766 g ITPG were dissolved in 20 mL multipore-H2O, sterilized by filtration, filled in 2 mL tubes and stored at -20°C.

3. DYT (5 litres)

  • 80 g Bactotrypton, 50 g Bactoyeast, 25 g NaCl were weight out.
  • 2 L multipore-H2O were added
  • after mixing, multipore-H2O was added -> endvolume 5 litres
  • medium was filled into flask and was autoclaved

4. Glycerol:

  • Glycerol was filled into a flask and was then autoclaved

To do: register at Mr. Gene!!!

9. Labday 17.05.2010

β-Globin

Investigators: Bea, Chris W., Patrick, Hanna (and instructors)



We blasted the sequence of the β-globin and additional nukleotides „vorne und hintendran“. We found only 70% coverage with the human β-globin-intron add. some parts of the exon 3. For this reason we think that the pAAV_MCS annotation of the β-Globin-intron of Stratagene is too generously.
In addition the alignment of the human ß-globin showed that only parts of the intron 2 (5’) and exon 3 are integratet into the vector. We assume that the informations from Stratagene are not total correctly ( intron flanket by the splicedonors and the acceptor-sequence). We blasted the sequence between the CMV-promoter and the origin beginning of the ß-globin intron. We found a 98,8% coverage with a synthetic CMV-promoterconstruct ( 1 nucleotide difference). Literature: „Diverse plasmid DNA vectors by directed molecular evolution of cytomegalovirus promoters. (Wright A. et al.)“
→The question arises if we can omit the ß-globin (because the exact function is unknown). For this we should contact various Companys (GeneArt, DNA2.0, Mr. Gene,…) to get more information. In addition we could test the expression with and without ß-globin.

Picking clones

Investigators: Adrian, Bea


    Clones were picked according to the standard protocol.
    • 3 approaches from each plate

13. Labortag 21.05.2010: CMV-Promoter


Theoretical cloning: (Volker, Hanna)

  • The CMV promoter (mainly the regulatory region) was further characterized: For this purpose U.S. patent no. 5,385,839 was used. Media:Freiburg10_Patent_US5385839A.pdf
  • Further on the CMV promoter sequence was blasted. The results delivered a 98% query coverage with the "Human herpesvirus 5 strain Toledo, complete genome" (accession no.: GU937742.1). Interestingly the maximal identity was just 99%. This can be explained due to a nucleotide deletion and a C-T transition (red circles), which were also marked in Geneious.

Freiburg10 CMV-Alignment.jpg
Freiburg10 CMV.jpg
To do: find "+1"-location (transcription start); which transcription factors bind to the regulatory region of the CMV promoter?

LB medium was prepared: (Patrick and Chris W.)

  • 10 g Bacto-Tryptone, 5 g Bacto-Yeast, 10 g NaCl were mixed in 500 mL milipore-H2O.
  • Volume was adjusted to 1 L with milipore-H2O.
  • 100 mL flasks were each filled with 50 mL medium.
  • 0.75 g agar was added to each flask.
  • LB was sterilized by autoclaving and is now stored at room temperature.

    Design of MCS-Oligos

    Investigators: Bea, Adrian, Hanna, Sven


    In order to replace the multiple cloning site of the pAAV_MCS vector from Stratagene by RFC25, two oligos were designed. After their hybridization the overhangs correspond to ClaI- and BglII restriction sites. A digestion with BglII and ClaI will be performed with pAAV-MCS and then will be ligated with the designed oligos.
    The oligos (see link) were ordered at Sigma-Aldrich. Estimated shipment: 31.05.2010 .

    Oligos (PstI + MCS)

    • Repeat cloning of pAAV-MCS + pCMV_mVenus_YFP --> Goal: pAAV_mVenus_YFP
      Cloning did not work (see lab day 25.05.2010) either with NotI or with NotI-HF. Gel did not show any proper band at the expected size.
      There will be used EtBr instead of gelred in the agarose gel and the incubation time of digestion will be prolonged. Further details are followed.
      NOTE: There are three restriction sites of NotI in the pCMV-mVenus_YFP. If cloning with NotI, the polyA hGH signal will be deleted. therefore cloning with NotI is not possible .

        Results: Test digestion of pCMV_MCS with NotI delivered plausibel results (expected fragment size: ~ 27 kbp and 17 kbp). Unfortunately the digestion of pCMV_mVenus_YFP with PstI and MluI resulted in one 2.9 kbp and one 1.2 kbp fragment, which didn't correspond to the expected fragment sizes of 19 kbp and 33 kbp - but to fragment sizes of pCMV_MCS without mVenus_YFP!

        (Hanna)
        The competent E.coli XL-1-blue and competent E.coli BL21 which were prepared the day before were test-transformed with pUC18 - following the standard protocol. Cells were plated on agar plates containing ampicillin and stored over night at 37°C. Further on two control plates containing ampicillin or kanamycin were prepared. Non-transformed cells were plated on them and also stored over night at 37°C.

    pAAV_RC R585A and R588A transistions

    In order to alter the tropism of AAV2 several modifications have to be performed. First of all the binding to Heparan Sulfate Proteoglycan has to be disrupted. This can be done by R585A and R588A transistions: Freiburg10 R585A R588A.jpg
