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
 +
<br>
 +
2. Rep-Gen:
 +
* delete EcoRI (2x) and PstI (2x)
 +
<br>
 +
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:<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>
 +
<b>To do: which bp, which sequence could/can be insertet? cf. the genome of AAV2</b> <br>
 +
<br>
 +
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.
 +
<br>
 +
5. enzymes:
 +
* Thymidinkinase: find informations. TK30 (Bea), SR39 (Hanna)
 +
* Cytosindeaminase: find informations (Adrian)
 +
<br>

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

<b>Investigator: Bea <br /></b>

-
<p style="font-size:13px; color:#66bbff;">Primers for different cloning strategies of the synthesized cap gene into pAAV_Rc have been designed.</p>
+
-
<ol>
+
-
<li>The first primers are mutagenesis primers which delete the KpnI recognition site at position 3968. These primers can (or should be used) be used if cloning with BspMI/BfuI (isochizomer) does not cut the pAAV_RC efficiently. Instead of using this enzyme we can use XcmI to subclone the cap gene with performing a site-directed mutagenesis afterwards with designed primers. </li>
+
-
<li>The second idea is to design oligoduplexes (hybridized oligos) which contain the recognition site for BspMI. In Gormley et al (2002) the idea was to add oligodupexes with the recognition site for BspMI and therefore provide the "second recognition site" in trans. </li>
+
-
</ol>

-
<b>Next step:</b> Check primers and order them today! Designed primers are stored in my Workingfolder under paav_rc and a word document was created whcih can be found under Oligos --> primers for different strategies...

'''T4 Ligation:'''<br />
+
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.
-
The  Ligation was performed as following:<br />
+
For this reason we think that the pAAV_MCS annotation of the β-Globin-intron of Stratagene is too generously.<br>
-
<p style="font-size:13px; color:red;"><b>Comment</b>: No sufficent vector concentration, therefore 5 µl of vector was used for every approach. </p>
+
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.
-
* Vector Volume: 5 µl
+
We assume that the informations from Stratagene are not total correctly ( intron flanket by the splicedonors and the acceptor-sequence).
-
* Insert Volume: 3 µl
+
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.)“<br>
 +
→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.

We analyzed the new sequencing results and found two correct sequences:

*587 BAP clone 2.3
 
-
*453 RGD clone 4.3

-
The other samples didn't contain any inserts or had wrong insertions. Apparently, the vector tends to religate easily. A possible reason for the religation of the incompatible ends is the overnight ligation at 18°C. We sent preps of the remaining 7 ligations for sequencing and will prep new clones or repeat the ligation tomorrow, depending on the new sequences.

* 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.

<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>

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)

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.

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.

    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)

    Investigators: Bea, Hanna, Jessica

    • 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!
