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.

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.

PstI or BstEII seems to work not properly
