Q5 PCR on fragments 3 and 4

"By Charlène"

A Q5 PCR was made on fragments 3 and 4 for a gel extraction. Tm = 72°C. Elongation time = 1 minute. Problem : 25 cycles at the place of 30.

Q5 PCR of fragments 3 and 4

There is not enough product for the extraction gel : a second PCR was done with 30 cycles. It will be running on gel next Monday.

Plasmids extraction

"By Terrence, Alice and Mahnaz"

The following plasmids were extracted using the "Charge Switch-Pro Plasmid Miniprep" kit:

• pPS16_009 (GFP1-9) clone 4
• pPS16_009 (GFP1-9) clone 5
• pPS16_014 (sgRNA Nm) clone 1
• pPS16_014 (sgRNA Nm) clone 2
• pPS16_013 (FKBP) clone 3
• pPS16_013 (FKBP) clone 4
• pPS16_013 (FKBP) clone 5
• pPS16_010 (FRB) clone 2
• pPS16_010 (FRB) clone 3
• pPS16_010 (FRB) clone 5
• pPS16_002 (1.2) clone 1
• pPS16_002 (1.2) clone 11

Colony and Extraction product DreamTaq PCR

"By Léa and Naiane"

A Colony PCR was performed on Dh5a transformed with PJet containing sgRNA Nm or 1.2 gBlocks. sgRNA Nm clones 6, 7, 8, 10, 11 and 12 were screened, and 1.2 clones 13 to 18 were screened and plated on Petri dish containing solid LB and Ampicilin.

In the meantime, a DreamTaq PCR was performed on plasmids extractions listed above, using the same PCR mix. The PCR mix was made following the usual protocol. Universal primers for PJET were used (Tm= 51.9°).

A previous step of denaturation (95°C, 5min) was performed for colony PCR.
