Colony PCR of Cloning VP2 Fusion and Super constructs into pSB1C3

Investigator: Achim, Hanna

Comment: Because yesterday's cloning didn't deliver a good separartion of the expected gel bands. Nevertheless ligation and trafo was performed. In order to immediately find out, whether we received successful results a colony PCR will be performed.
Two clones were picked from each plat. In addition to that a positive (pAAV_RC) and a negative control (pSB1C3_lITR) was prepared.
Used primer: 4200 rev and Cap3500 for. Expected fragment size: 885 bp.
PCR was performed following the standard protocol.

All samples match the positive control!
To do: Mini-Prep and sequencing.

Preparation of SDS gel (10%)

Investigator: Hanna

Comment: In order to perform a Western Blot of different virus capsids (with and without capsid-motifs), a 10% SDS polyacrylamid gel was prepared.

Colony PCR of p40_VP123_capins

Investigator: Bea

Comment: Since the first attempt did not work,and no cells grew on the plate and the same ligation was transformed again into BL-21 and a lot of clones grew on the plate, I decided to perform a colony PCR in order to check several colonies and to inoculate at the same day for a Midi-Prep.

Protocol:

• Primer used: O162
• Primer used: O38

The PCR products were loaded on a 1% agarose gel. The results can be seen above in the gel picture:

Result: We can see two things: The cloning of p40 to VP123 worked quiet well AND the Robust PCR Kit which was used for the first time worked as well.

cloning of lITR_CMV_betaglobin and lITR_phTERT_betaglobin into pSB1C3_CD

Investigator: Stefan

Comment: To produce another GOI for testing in cell culture, the cytosine deaminase needs to be assembled with lITR_promotor_betaglobin. In the next step hgH_rITR needs to be added.

Vector name:
pSB1C3_CD clone 1 (P???)
pSB1C3_CD clone 2 (P???)

Insert name:
pSB1C3_lITR_CMV_beta-globin (P729)
pSB1C3_lITR_phTERT_beta-globin (P730)

Digestion:

Gel:
0,5 g Agarose, 50 ml TAE (1%), 3 µl GELRED , at 115 Volt

CD clone 1 yielded to bands around 2500 bp to 3000 bp. Since the vector was cut only using EcoRI and SpeI, it was expected to be linearized, not to be cut into two fragments this size. Therefore, this sample was discarded and cloning was continued using CD clone 2.

Gel extraction:
Was performed according to protocol.

T4 Ligation:

Transformation:
Was performed according to standard protocol using BL21 cells.
