*Sequencing showed that clone 2 had a mutation in the vector, clone 3 had one in the BLA sequence. Therefore, both were cut with BamHI and SalI, then the BLA fragment of clone 2 and the vector fragment of clone 3 were ligated. The final construct shouldn't contain any more mutations.

<b>Comment:</b> The CMV promoter is often used in combination with a SV40 terminator. Because we want to use this promoter in the context of the VP2 fusion and VP1 insertion approaches, oligos were designed in order to produce a SV40 terminator BioBrick (from the pEGFP-C1 plasmid).

 +
<b>Comment:</b> In order to perform the VP2 N-terminal fusion and VP1 insertion approaches, we decided to use pEGFP-C1 as expression plasmid. This plasmid contains an EGFP under the control of the CMV promoter and the SV40 terminator. In order to exchange the EGFP with our targeting constructs a PCR of the CMV_backbone_SV40Terminator should be performed. The referring primers were designed with EcoRI and PstI restriction sites. One should keep in mind that this expression plasmid mustn't digested with NgoMIV and it contains Kanamycin-resistance!

Again there was a bacterial lawn on the agar plate. Therefore some clones from the overgrown agar plated were picked and diluted. The 1:10^4, 1:10^5, 1:10^6 dilution each were put onto an agar plate (37°C, over night). Additionally a transformation with XL1B cells from the remaining SDM DNA sample was performed and diluted, too. The 1:10^4 and the 1:10^6 dilution were plated. Hopefully there will be some 'pickable' clones tomorrow.

Investigators: Volker
 +
 +
 +
The aim of this experiment is to assemble the affibodies with the the five linkers and the YFP with the His-Tag. All cloning is done according to RFC 25 and will be used to test the affibody if it really binds the EGF-receptor, for the N-terminal fusions and to supply it to other groups in the registry.<br>
 +
 +
This experiment went wrong on Saturday 21.08. and was repeated on Sunday 22.08. and gave the following results. Results from the first experiment are not shown but can be senn in the written Labjournal.

<br />
 +
 +
<b>The Motivation</b><br />
 +
Transfection of AAV293 cells from 19.8 (ten 10cm<sup>2</sup> dishes with 2.000.000 cells each) <font size="4" color="#F0000">with original standard protocoll!!!</font> We want to try different 2xHBS Buffers (pH) and their influence on transfection efficiency!<br /><br />
 +
<b>The Plan</b><br />
 +
<br />
 +
<b>Requiered goods</b>: 0,3 M CaCl<sub>2</sub> , 2x HBS-Buffer , autoclaved millipore water, falcons, eppis
 +
<br />
 +
<b>Working steps</b>:
 +
<ol>
 +
<li>Remove the three plasmids to be co-transfected (the recombinant  pAAV expression plasmid or control plasmid, pAAV-RC, and pHelper)  from storage at –20°C.</li>
 +
<li>Pipet 10 µg of each of the three plasmid DNA solutions into an eppi.</li>
 +
<li>Add 1ml of 0.3 M CaCl<sub>2</sub> and mix gently</li>
 +
<li>Pipet  1ml of 2 × HBS  into a 15-ml falcon.</li>
 +
<li>pipet the DNA/CaCl<sub>2</sub> solution dropwise into the falcon (use the Pipetus).</li>
 +
<li>Apply the DNA/CaCl<sub>2</sub>/HBS suspension to the plate of cells in a dropwise fashion, swirling gently to distribute the DNA suspension evenly in the medium.</li>
 +
<li>Return the tissue culture plate to the 37°C room for 6 hours.</li>
 +
<li>At the end of the incubation period, remove the medium from the plate and wash cells with warm PBS, replace it with 10 ml of fresh DMEM growth medium.</li>
 +
<li>Return the plate to the 37°C incubator for an additional 72 hours.</li>
 +
</ol>
 +

 +
<p style="font-size:13px; color:#68bbff;">'''''Comment''''': Mini-Prep of pSB1C3_SDM_SspI_Bla14FM showed extremely low plasmid concentrations. It was proposed that this could correspond to using not the standard lab cells but rather XL-10 Gold cells for trafo. Therefore a re-trafo was performed using BL21 cells. 2 µl of each clone was added to BL21 cells and trafo was performed. Clones can be picked tonight (Volker)!</p> <br />

<b>Investigator: Bea</b><br>
 +
<p style="font-size:13px; color:#003399;"><b>Comment</b>: Two goals will be accomplished with this primers.
 +
<ol>
 +
<li>The first primer pair (left picture) serve as sequencing primers for the pSB1C3 vector plasmid. Problem was that the designed VR-2/VF-2 primers cannot be used for sequencing because the ITRs flank several assembled parts, mostly CMV, beta globin, GOI and hGH. These primers were designed to bind in the flanked region, directly after/before left and right ITR repsectivel and can therfore be used to sequence most of the flanked sequence inbetween the ITRs.</li>
 +
<li>The second primer pair (right picture) will be used for performing the qPCR with th econtruct containing the phTERT promoter. The qPCR primers used for the other qRT-PCR cannot be used because these two primers anneal in the CMV region. The new designed primers bind in the phTERT region and can therefore bee used for determinining the infectious titers.</li>

Picking clones of pSB1C3_CMV

Investigator: Bea

Comments: Trafo was performed friday, and trafo plate were incubated over night. Clones need to be picked in order to perform Mini-Prep

  • Bacterial strain used: XL1-B
  • Two clones were picked of trafo plate
  • Inoculating of 10 mL DYT medium containing 10µL chloramphenicol
  • Put in 37°C room on rotary shaker

Sequenzing of pSB1C3_RFC25_longlinker, pSB1C3_RFC25_SEG, pSB1C3_RFC25_GSAT

Investigator: Jessica

Comments: Linkers (we got from Gerrit) we cloned in the RFC25-standard (pSB1C3_RFC25). Result looks good, linkers are in the vector pSb1C3_RFC25

  • pSB1C3_RFC25_longlinker P105 und P106
  • pSB1C3_RFC25_SEG P107 und P108
  • pSB1C3_RFC25_GSAT P109 und P110

Sequencing of pGA14_Prefix-leftITR

Investigator: Hanna

Eventually GATC partially managed to sequence pGA14_Prefix-left ITR clone 1 and 2.
The sequencing results were better than before but in the ITR region still not evaluable due to the strong secondary structures.

It seemed that, despite of successful insertion of the RFC10-Prefix, something went wrong because there were 2 bases missing in the NotI restriction site. But by having a closer look, it became obvious that the Geneious misinterpreted the chromatogram and overlaid the peaks of the missing bases.

LeftITR+Prefix.jpg

For the first time sequencing of parts of the 3' end worked: The remaining NotI restriction site, which was already eliminated this week and also the "backbone-PstI" can be seen:

LeftITR+Prefix 2.jpg

Sequencing of very GC-rich regions :) :) :)

LeftITR+Prefix 3.jpg

Sequencing of clone 4 delivered that the ITR and the RFC10-Prefix were not inserted in the vector. The RFC25 standard of the multiple cloning site is still in the plasmid:

LeftITR+Prefix clone4.jpg

Therefore clone 4 was dicarded from the plasmid- and glycerol stock.

Repetition of test digestion pSB1C3_CFP SDM SspI and PvuII

Investigator: Jessica

  • buffer used: 2; Restriction-enzymes used: Enzyme 1: SspI ; Enzyme 2: PvuII

Freiburg10 Gel test digestion SDM.jpg
























  • P125 isn't cut, therefore you see the bands for supercoiled, nicked and relaxed
  • P51.1 is cut once, therefore you can see a faster running band
  • P129 and P131 should be cut once because of the PvuII in the CFP but there is another band we can't identify
  • P51.1 should be cut two times but there is also another unidentified band
    • perhaps there is another PvuII in the vector we can't find (???)

Comments: SDM of SspI is ready! SDM of PvuII looks confusing because of the lower band. P 129 will be sequenced but this doesn't solve this problem. there has to be one more rs we don't know, perhaps. we will check it...anywise

Afer 50 minutes a picture (see below) was taken. Because there was no clear pattern (two bands) for the pSB1C3 backbone, the band of the insert mGMK was cut out and the gel ran another 20 minutes. After that, there were still two bands. Both were cut out and it was continued with two possible backbones. They were labeled vector (lower) and vector (upper).

Plasmid was transformed into BL21 cells. Clones have to be picked tomorrow.

Comments:NO CLONES, trafo didn't work, because annealing temperature was totally to high! (80,4 °C instead of 55°C) annealing temperature should always be 55°C (in case of troubleshooting temperature can be increased up to MAX. 68°C !)


PCR for Biobrickproduction of Rep 40, 52, 68, 78 and APP

Investigators: Volker, Anna


Aim of the experiment: We wanted to produce biobricks from the expression plasmids Rep40ex, Rep52 ex, the Rep 68 and 78 in which the PstI at position 310 was silenced and the AAP. This was performed by a PCR with primes that annealed to the ends of the later biobrick but also contained restriction sites that can be cut afterwards and cloned into pSB1C3.

  • Plasmids used as template:

Rep_68_ex (p119): c = 470,6 ng/µl
Rep_78_(p122): c = 201,08 ng/µl
Rep_40_(p22.2): c = 673,1 ng/µl
Rep_52_(p23.2): c = 532,22 ng/µl
pAAV-RC containing AAP ORF (p50): c = 378,5 ng/µl


  • Primer used:

For Rep_40_ex: Praefix_40_52_ex & Suffix_40_68_ex
For Rep_52_ex: Praefix_40_52_ex & Suffix_52_78_ex

Five µl of PCR-product were used for an analytical gel to see if the PCR worked.

BioBrick production for Rep and AAP

Alalytical gel

Praeparative gel

Comment: The result is that the PCR worked for the longer Rep proteins (68&78) with which a Quick-change was performed to remove the PstI(310) but not with the constructs for the smaller Rep variants (40&52) that were recieved from PD Kleinschmidt. As the longer Rep variants the AAP PCR Reaction also resulted in a PCR-product of the expected size. Unfortunately there were a secondary band of ~90bp for Rep_68_ex. For this reason we performed a praeparative gel and decided to cut the bands of all PCR products.


The bands marked in the gel picture were cut and a gel extraction was performed.

preparation of competent XL1blue was finished according to the standard protocol

  • aliquots of 60µl (to use for 1 trafo) are stored in -80°C freezer

Sequencing of pSB1C3

Investigator: Jessica

Comments: We sent for sequencing pSB1C3_RFC25_longlinker (P105) to check the strange result of the test digestion of pSB1C3_SDM_PvuII(01.08.10.
pSB1C3_SDM_PvuII is too long for sequencing wherefore we sent pSB1C3_RFC25_longlinker because the longlinker just have 54kb (bp, nicht kb (Volker) (necessary is just the backbone we don't have.

    Plan for the next virus production procedures
    The Motivation: investigation of the influence of different GOI amounts.
    The Plan: keep rep/cap and pHelper amount stable (3,3 µg each => 6,6 µg), differ the GOI (YFP) amount in each stock.
    Viral Stocks:

    • 3,3 µg YFP + 3,3 µg pHelper + 3,3 rep/cap
    • 10 µg YFP + 3,3 µg pHelper + 3,3 rep/cap
    • 20 µg YFP + 3,3 µg pHelper + 3,3 rep/cap


    • 3,3 µg pHelper + 3,3 rep/cap (without GOI !!!)

    Sequencing results of ITRs

    Investigator: Hanna
    8 sequencing files were analyzed "per hand" base by base. Alignments (will be inserted soon) delivered that the right ITR is 100% OK and was successfully converted into the RFC10 BioBrick standard.

    Freiburg10 Sequencing RFC10RightITR 2.jpg

    The sequencing and alignments of the left ITR delivered that a 15 bp fragment in the middle of the sequence is lacking. Therefore further test digestions have to be performed. Nevertheless also this ITR was successfully converted into the RFC10 BioBrick standard. Secondary structure analysis showed that the stemloop-structure will be nevertheless forming. We will try to test whether the referring fragment is also missing in the pAAV_MCS. If it's also lacking there we will continue with this ITR and test whether it functions.

    All marked fragments were extracted. The Gelextraction was performed according to the standard protocol following a digestion of the PCR products with EcoRI HF and SpeI and a purification of the PCR product. The Ligation was not performed according to the standard protocol: 1 µl T4 DNA Ligase, 1 µl (10x) Buffer, 3 µl vector pSB1C3 (60 ng/µl) and 5 µl insert (all concentrations about 100 ng/µl). The Transformation (with BL21) was performed according to the standard protocol. Tomorrow there will hopefully be some clones on the agar plates.

    BioBrick Assembly of pSB1C3_beta globin_mVenus

    Investigator: Bea

    Comments: BioBricks are ready to use. The sequenced pSB1C3_beta globin (P133) and pGA14_mVenus (P60) will be digested with different enzymes and will be assembled in order to produce the first step in assembling the whole vector together.


    • First the plasmids P133 and P60 were digested:
      pSB1C3_betaglobin/µL pGA14_mVenus/µL
    DNA 7 9
    BSA (100x) 0,2 0,2
    Buffer 4 (10x) 2 2
    Enzyme XbaI 1 1
    Enzyme AgeI 1 1
    H2O 8,8 6,8
    Total volume 20 20
    • Incubation of plasmids at 37°C for 2 hours
    • Load samples on preparative 1% agarose gel and run at 110 V, 45 minutes


    Results: As it can be seen in the picture below, digestion of the vector pSB1C3_betaglobin (left lane) revealed a band at around 2500 - 3000 bp. The expected size after digetsing with SpeI and PstI was: 2555 bp. The band ran a little bit higher than expected, anyhow the band was cut out of the gel. The right lane belongs to the pGA14_mVenus which was digested with XbaI and PstI which resulted in two fragments. mVENUS was digested. Expected sizes were: mVenus = 756bp and pGA14 = 2900bp. The expected sizes correspond to the bands seen in the picture below. The smaller fragment belonging to mVenus was cut out of the gel as well.

    Freiburg10 pSB1C3 betaglobin mVenus 06 08 2010.jpg

    After gel extraction has been performed, the concentrations of the two fragments were measured and we obtained following concentrations:

    • c(pSB1C3_betaglobin) = 15,62 ng/µL
    • c(mVenus) = 6,83 ng/µL


    For ligation the T4-Ligase were used.

    • v(pSB1C3_betaglobin) = 2,64 µL
    • v(mVenus) =5,36 µL
    • v(10xT4 Ligase buffer) = 1 µL
    • v(T4-Ligase) = 1 µL
    • Total volume = 10 µL


    Additionally a control ligation was performed.

    • v(pSB1C3_betaglobin) = 2,64 µL
    • v(H20) =5,36 µL
    • v(10xT4 Ligase buffer) = 1 µL
    • v(T4-Ligase) = 1 µL
    • Total volume = 10 µL
    • Ligation duration was 45 minutes on room temperature.


    After ligation a transformation was performed.

    • Used bacterial strain: XL1-B
    • LB-agar plates containing chloramphenicol were plated and put in the 37°C room over night


    To do: Mini-Prep and test digestion in order to verify assembly of beta globin and YFP. After verification of the fusion of the two fragments this construct is ready for the next BioBrick assembly step.

    ITR test digestion of pAAV_MCS

    Investigator: Hanna

    Comment: Because sequencing of the right ITR delivered that perhaps a 15 bp fragment is missing in the sequence, we wanted to check, whether this fragment is also not present in the original pAAV_MCS plasmid or whether the loss of these 15 bp happened during cloning.

    Freiburg10 testDigestion pAAV MCS.jpg

    Comments: The test digestion showed that there're two bands between the 100 and 200 bp marker nucleotides! By comparing the gel picture with the last mini-prep digestion of the fancy method we found out that the space between the two bands are similar. Because of that we assumed that the 15 pb are already missing in the original Stratagene plasmid!!!


    Conclusion: Because we already tested the Stratagene Kit via YFP expression, we can conclude that the usage of the "wrong" rigth ITR works. Therefore we decided to continue working with this "mutated" = ENGINEERED  :) right ITR as BioBrick.

    Continuation: Cloning Rep40 & Rep52 into pSB1C3

    Investigator: Patrick
    Results: no clones could be picked because there were no clones. Maybe the PCR purification or one of the following steps did not work (the PCR purifications were quite bad) so i purified the PCR products again yielding very low DNA concentrations (0-13,28 ng/µl) and still very obvious pollution of the sample. Nonetheless a ligation with the insert Rep40+DMSO, Rep52, Rep52+DMSO and the vector pSB1C3 was carried out following a transformation and according to the standard protocols. Hopefully there will be some clones tomorrow.

    Comment:

    Comments:Oh f... it makes no sense... if the cloning didn't work, there can just be 3 bands (one time SspI and twice PvuII). The results of the test digestion from aug 1th showed that there can be one RS PvuII more. but then you have a maximum of 4 bands. P157.2 show 5 bands. i can't interpret this result at the moment. interpretation will follow

    Retrafo with RepCap gene (Mr.Gene)

    Investigator: Bea

    Comments: We received the rep_cap insert ordered from Mr. Gene today. In order to used and clone the insert into the desired sequences a retrafo has to be performed.

    Re-transformation:

    • Construct used: pMA_REP_CAP
    • We reveived 5 µg (lyophilzied). These were resuspended in 100 µL H2O and vortexted.
    • c = 50 ng/µL
    • c = Plasmid need to be diluted in order to obatain the final 500pg
    • Dilution: 1:100
    • 100 µL aliquot of XL1-B were thawed on ice. The proper amount of 1µL was added to the cells.
    • Transformed cells were plated on LB plates containing ampicillin

    Continuation: Cloning Rep40 & Rep52 into pSB1C3

    A midi prep of the two Rep52+DMSO clones was performed yielding concentrations of 261,35 ng/µl (clone 1) and 240,47 ng/µl (clone 2). Unfortunately we noticed today that we should not use EcoRI to clone Rep52 into pSB1C3 because EcoRI cuts two times within the sequence of Rep52.

    Midi-Prep of pAAV_RC, pAAV_RC_1.2 SDM SalI (P158), pAAV_RFC25_mGMK_TK30 clone 1 (P81) and 2 (P82)

    comments: Test digestion of pSB1C3_SDM_SspI/PvuII with ClaI, BpmI and SspI looks the same as with ClaI and BpmI. Therefore we can assume that there is no additional restriction site within the vector. But still the bands above 3000 bp cannotz be explained. A new test digestion will be performed tomorrow to check the size of the vector.
    The approach cut with ClaI, BpmI and PvuII looks strange. Propably, PvuII does not work correctly. New PvuII-HF was ordered and delivered so this can be verified tomorrow.
    pSB1C3_RFC25_longlinker digested with SspI and PvuII seems to be not completely digested This could correspond to non-working PvuII. pSB1C3_CFP looks like expected.

    Quickchange of the EaglII restriction site in the PMA_RepCap vector

    Investigator: Chris L., Achim

    Comments: We performed a QuikChange mutagenesis on the synthesized PMA_RepCap vector (P190). The EaglII restriction enzyme also cuts NotI (IGEM standard) therefore EaglII has to be changed into a different recognition site. Primers were designed to change it into PvuII. The new QuikChange Lighting Site-Directed Mutagenesis Kit from Stratagene was used, therefore the mutagenesis was carried out as described in the QuikChange Manual. The PCR product was transformed into XL10-Gold cells, we used the IGEM standard protocol, except for the addition of ß-ME to the XL10-Gold cells.  :

    Sequencing results of Rep68, Rep78 and AAP BioBricks

    Investigator: Hanna
    Comment: pSB1C3_Rep78 (P160), pSB1C3_Rep68 (P165) and pSB1C3_AAP (P170) were sent for sequencing twice. No sequencing made sense. Paradoxically the Rep78 sequencing result fit to the p5 promoter BioBrick...
    By having a closer look to the BioBrick PCR we found out that the fragment sizes didn't fit to the expected sequences. In addition to that the test digestion also showed some discrepancies.
    Because we weren't able to find out in which steps of the BioBrick production things went wrong, we decided to discard all referring glycerol stocks and plasmids and to perform the Rep68, Rep78 and AAP BioBrick PCR again!!!

    Comment 13.08.2010 (Hanna): We wondered how the whole Rep stuff could be sequenced reverse AND forward without any forward sequencing primer... By checking the "sequencing book" we found out that always the wrong primers were used: the GOI primers can be used in order to sequence the Gene of interest = GOI (!) in pAAV_MCS and NOT the pSB1C3!!!!!!!!!

    Opened a BioBrick box

    Investigator: Bea
    In order to "save" the plasmids/BioBricks which has been prepared and confirmed for submitting it to the parts registry a new box have been prepared. The box should contain 30 µL of the desired construct cloned into the pSB1C3 vector and the BBa number given from the headquarter.

    The first BioBricks which are in this box are:

    • pSB1C3_hGH (P136): Bba_K404002
    • pSB1C3_betaglobin (P133: Bba_K404001

    • pSB1C3_mGMK (P156): Bba_K404004

    In our nomenclature plasmid excel list the constructs which we aliquoted should be highlighted in blue and commented with the given Bba number. Additionally it should be taken in consideration that enough DNA should be in the "working" plasmid box. Therefore, if necessary, inoculate DYT medium for Mini-Preps.

    In this case ALL the glycerol stocks were used for incoluating 10 mL DYT medium containing 10 µL chloramphenicol respectively.

      To do: Mini-Preps of the over night cultures.

    Design and ordering of oligos for VP fusion targeting approaches

    Investigator: Hanna

    Comment: In order to target the EGFR receptor of our A431 cells different approaches have been figured out: Besides loop insertions, N-terminal fusion to the VP2 protein will be performed. In addition to that a VP1 insertion approach (after Grieger et al., 2007) was planned.
    Fusion and insertion molecules will be e.g. His-tag, Affibody, Darpin, GFP. These approaches can be combinated with the loop insertions.
    For this purpose the following oligos were ordered today:

    Sequence analysis of pSB1C3_SDM_SspI_BLA

    Investigator: Patrick, Bea

    Comments: Sequence analysis of three clones revealed that all sequences contain some mutations in the regions where the primer annealed. This was due to the extreme primer lentgh. Primers that long should be ordered as HPLC purified in order to avoid mutations in the primer sequence.

    1. Clone 1: Mutation in the SalI site of the loop insertion site in the Viral Brick MCS lead to the removal of the recognition site. CANNOT be used for the loop insertions!!!!
    2. Clone 2: Mutation in the region of the primer upstream of the loop insertion sites SalI and PvuII.
    3. Clone 3: Mutation in the region of the primer downstream of the loop insertion sites SalI and PvuII.

    Clone 2

    Clone 3


    Next steps: Two additional clones will be picked and sent for sequencing (clones 4 and 5). In order to obtain a construct without any mutations, clone 2 and clone 3 couldbe cloned together. Each clone will be digested with SalI and BamHI. Clone 2 will be the "insert", clone 3 is going to be the "vector". Therefore the fragments will (hopefully) not contain anymore mutations in the relevant sequence.

    Results of test digestion

    Freiburg10 Test digestion of pSB1C3 Bba fourparts SDM pMA RC insert 14 08.jpg


    Results: Two (three) different approaches can be seen on the agarose gel.

    1. P178-P181 (blue): The plasmid pSB1C3_leftITR_CMV_betaglobin_mVenus was digested with NgoMIV and EcoRI. Expected bands were: 2873bp and 1343 . As it can be seen in the picture, the two fragments ran too high (~300bp). As it is almost normal for the pSB1C3 plasmid, we should figure out why this is always the problem for this vector.
    2. P182-P183 (red): The plasmid pMA_RepCap_SDM_insPvuII was digested with PvuII as well as the control vetor pMA_RepCap where no site-directed mutagenesis was performed in order to see the difference. As it can be seen in the picture above, the expected band sizes of 263bp,1384bp and 2133bp correspond to the bands detected in the gel. The control vector instead reveals only two bands detectable. Therefore site-directed mutagenesis was successfully performed.
    3. P177 (green): pSB1C3_hTERT. For further details see extra part below (Test digestion of pSB1C3_hTERT.

    Test digestion of pSB1C3_pHTERT

    Investigator: Bea

    Comments: pSB1C3_hTERT was sent for sequencing and revealed that the PCR and the inserting of the PCR product : promoter for hTERT was sucessfully performed. But the sequencing results showed a new AgeI restriciton site in the plasmid backbone. We could not see if the new recognition site was due to the bad sequence read or that there is really a new AgeI site. Therefore, a test digestion will be perfomed with PstI and AgeI in order to figure our wheter AgeI is present in the backbone or not.

    Result of the test digestion:

    Test digestion of pSB1C3_hTERT
    Freiburg10 Testdigestion pSB1C3 hTERT 14 08.jpg


    Results: As it can be seen in the sequencing results of pSB1C3_hTERT there could have been an additional AgeI site in the vector. If AgeI would have been in the vector, two fragments have been expected by digetsing the plasmid with AgeI and PstI. As it can be seen in the agarose gel, lane 11 (labeled with the green P177) only reveals one lane instead of two. Therefore it can be assumed that NO AgeI site is in the pSB1C3 backbone.

    Sequencing results of pSB1C3_Rep52 clone 3
    Freiburg10 Sequence analysis of pSB1C3 Rep52 14 08 2010.JPG


    Results:

    Sequence assembly showed that the suffix of the Rep protein 52 is ok and that PCR worked well.

    There can be seen that a silent mutation from AGG to AGA was inserted, but it will have no effect on the protein because codon usage in H. sapiens is nearly the same for both codons.

    The prefix could not be analysed because of bad sequence read quality. For further verification, another sequencing with the forward primer has to be performed.
    Next steps: Send plasmid for another sequencing round with forward primer in order to analyse the prefix.

    Investigator: Achim

    • Sequencing showed that clone 2 had a mutation in the vector, clone 3 had one in the BLA sequence. Therefore, both were cut with BamHI and SalI, then the BLA fragment of clone 2 and the vector fragment of clone 3 were ligated. The final construct shouldn't contain any more mutations.

    Design and Ordering of Oligos

    Investigator: Hanna

    SV40 terminator

    Comment: The CMV promoter is often used in combination with a SV40 terminator. Because we want to use this promoter in the context of the VP2 fusion and VP1 insertion approaches, oligos were designed in order to produce a SV40 terminator BioBrick (from the pEGFP-C1 plasmid).
    Freiburg10 SV40Terminator.jpg

    pEGFP_backbone

    Comment: In order to perform the VP2 N-terminal fusion and VP1 insertion approaches, we decided to use pEGFP-C1 as expression plasmid. This plasmid contains an EGFP under the control of the CMV promoter and the SV40 terminator. In order to exchange the EGFP with our targeting constructs a PCR of the CMV_backbone_SV40Terminator should be performed. The referring primers were designed with EcoRI and PstI restriction sites. One should keep in mind that this expression plasmid mustn't digested with NgoMIV and it contains Kanamycin-resistance!

    Transfection of AAV293, Harvest viral particles, Transduction of HT1080 and Fluorescent microscopy

    Investigators: Adrian, Kerstin

    The Motivation
    Measure the Transduction efficiency from 19.8

    The Motivation
    Transfection of AAV293 cells from 19.8 (ten 10cm2 dishes with 2.000.000 cells each) with original standard protocoll!!! We want to try different 2xHBS Buffers (pH) and their influence on transfection efficiency!

    The Plan

    Requiered goods: 0,3 M CaCl2 , 2x HBS-Buffer , autoclaved millipore water, falcons, eppis
    Working steps:

    1. Remove the three plasmids to be co-transfected (the recombinant pAAV expression plasmid or control plasmid, pAAV-RC, and pHelper) from storage at –20°C.
    2. Pipet 10 µg of each of the three plasmid DNA solutions into an eppi.
    3. Add 1ml of 0.3 M CaCl2 and mix gently
    4. Pipet 1ml of 2 × HBS into a 15-ml falcon.
    5. pipet the DNA/CaCl2 solution dropwise into the falcon (use the Pipetus).
    6. Apply the DNA/CaCl2/HBS suspension to the plate of cells in a dropwise fashion, swirling gently to distribute the DNA suspension evenly in the medium.
    7. Return the tissue culture plate to the 37°C room for 6 hours.
    8. At the end of the incubation period, remove the medium from the plate and wash cells with warm PBS, replace it with 10 ml of fresh DMEM growth medium.
    9. Return the plate to the 37°C incubator for an additional 72 hours.


    We try 5 different 2xHBS buffers:

    • pH: 7.06
    • pH: 7.08
    • pH: 7.10
    • pH: 7.12
    • pH: 7.14
    • 1. Plate: 10µg of Rep/Cap, pHelper and GOI=mVenus; pH(2xHBS)= 7.06
    • 2. Plate: 10µg of Rep/Cap, pHelper and GOI=mVenus; pH(2xHBS)= 7.08
    • 3. Plate: 10µg of Rep/Cap, pHelper and GOI=mVenus; pH(2xHBS)= 7.10
    • 4. Plate: 10µg of Rep/Cap, pHelper and GOI=mVenus; pH(2xHBS)= 7.12
    • 5. Plate: 10µg of Rep/Cap, pHelper and GOI=mVenus; pH(2xHBS)= 7.14
    • 6. Plate: 10µg of Rep/Cap, pHelper and GOI=TKGMK; pH(2xHBS)= 7.08
    • 7. Plate: 10µg of Rep/Cap, pHelper and GOI=TKGMK; pH(2xHBS)= 7.10
    • 8. Plate: 10µg of Rep/Cap, pHelper and GOI=mVenus; pH(2xHBS)= 7.14



    The transfected cells were seeded at 19.8 (2.000.000 cells per 10 cm2)
    Used Plasmids: Standart protocol: 10µg of each plasmid

    • GOI: mVENUS => P262, conc:1148ng/µl; used amount: 8,71µl
    • GOI: TKGMK => P82b, conc:1500ng/µl; used amount: 6,67µl

    concentration (ng/µl)1035,10 1376,95


    Re-Trafo of pSB1C3_SDM_SspI_Bla14FM

    Investigator: Stefan

    Comment: Mini-Prep of pSB1C3_SDM_SspI_Bla14FM showed extremely low plasmid concentrations. It was proposed that this could correspond to using not the standard lab cells but rather XL-10 Gold cells for trafo. Therefore a re-trafo was performed using BL21 cells. 2 µl of each clone was added to BL21 cells and trafo was performed. Clones can be picked tonight (Volker)!

    Primer design: Sequencing primer for BioBrick Assembly of vectorplasmid and phTERT qPCR primer

    Investigator: Bea

    Comment: Two goals will be accomplished with this primers.

    1. The first primer pair (left picture) serve as sequencing primers for the pSB1C3 vector plasmid. Problem was that the designed VR-2/VF-2 primers cannot be used for sequencing because the ITRs flank several assembled parts, mostly CMV, beta globin, GOI and hGH. These primers were designed to bind in the flanked region, directly after/before left and right ITR repsectivel and can therfore be used to sequence most of the flanked sequence inbetween the ITRs.
    2. The second primer pair (right picture) will be used for performing the qPCR with th econtruct containing the phTERT promoter. The qPCR primers used for the other qRT-PCR cannot be used because these two primers anneal in the CMV region. The new designed primers bind in the phTERT region and can therefore bee used for determinining the infectious titers.

    Primer design. Ordered at Sigma Aldrich
