150. labday 15.10.2010
Cloning CFP (from P666: PSB1C3_CFP) into pSB1C3_leftITR_CMV_beta-globin (P729)
Investigator Patrick
Digestions, 2 h 10 minutes, 37 °C:
- P666: 5 µl DNA, 2 µl BSA, 2 µl Buffer 4 (10x), 1 µl Xba, 1 µl PstI, 9 µl H2O
- P729: 4 µl DNA, 2 µl BSA, 2 µl Buffer 4 (10x), 1 µl SpeI, 1 µl PstI, 10 µl H2O
Expected results for the 1% agarose gel:
- P666: about 2100 and 750 bp
- P729: about 3300 and 20 bp
The gelextraction ...
P728: 11,8 ng/µl
P822: 34,6 ng/µl
... and following ligation (2,5 µl Insert, 5,5 µl vector, 1 µl T4 DNA Ligase, 1 µl T4 DNA Ligase Buffer (10x), 40 minutes, RT) were performed according to the standard protocol. After the transformation (with XL1B) the cells were plated and put into the 37°C room.
Two additional transformations were performed with ligations from Volker labeled: "ligation viral brick 453 empty" & "viral brick 587 empty".
The following day the plates were checked for clones. Unfortunately there grew no clones on these two plates contrary to my plate with a a lot of clones.

After transfection, the cells were incubated for 48 hours. Today, the cells will be harvested and RNA extracted, in order to perform RT-PCR and an additional PCR for evaluation of promoter activity.
The transfected cells were trypsinised and centrifuged for 2 min. The supernatant was discarded and pellet washed 2x with PBS. RNeasy Kit [Qiagen] was used for RNA extraction according to the manufacturer protocol.

quantitative real-time PCR for detection of virus titer
Investigator: Achim
- qPCR of harvested virus particles to determine the virus titers of our different constructs
- Total number of samples: 58
Test-digestion of pSB1C3_lITR_phTERT_betaglobin_mGMK_TK30_hGH_rITR_SDM-PstI clone 1, 2 and 3 (P877, 878 and 879)
Investigator Patrick
Check the plasmid for leftITR:
0,5 µl EcoRI, 1 µl BstEII, 7 µl DNA, 2 µl Buffer 4, 2 µl BSA, 7,5 µl H2O, 45 minutes 37°C, 45 minutes 60°C
Check the plasmid for hGH_rITR and ... :
0,5 µl AgeI, 0,5 µl PstI, 3 µl DNA, 1 µl BSA, 1 µl Buffer 4, 4 µl H2O, 70 minutes 37°C
Expected results:
- leftITR: about 190 bp
- hGH_rITR: about 670 bp
Unfortunately the digestions had to be reapeated because i didnt switch on the current so the samples and especially the 1kb GeneRuler marker diffused.
The second run: see above
PstI or BstEII seems to work not properly
