Colony PCR of 16 clones containing FRB - GFP 11 - GFP 1.9 in pSB1C3 (pPS16_022)
By Maxence, Mahnaz & Coline
A colony PCR was done for 16 clones from the 20th September. For that purpose, 16 clones were screened and used for the usual protocol of Colony PCR. The same colonies were also plated on Petri dish containing solid LB + 30 µg/mL Cm and liquid cultures (LB + 30 µg/mL Cm) were made from these clones. Both petri dishes and liquid cultures were grown at 37°C.
For each clones contained in 20 μl water, 5.13 μL of the following mix were added :
- 2.5 µL DreamTaq Buffer
- 0.5 µL of dNTPs (10mM)
- 1 µL of each primer mix (10µM)
- 0.13 μl of DreamTaq Pol

Colony PCR of 16 clones containing FKBP - GFP 10 in pSB1C3 (pPS16_019)
By Maxence, Mahnaz & Coline
As sequencing results were not convincing, a new colony PCR was done for 16 clones from the 15th September but with primers iPS168 & iPS169. For that purpose, 16 were screened and used for the usual protocol of Colony PCR. The same colonies were also plated on Petri dish containing solid LB + 30 µg/mL Cm and liquid cultures (LB + 30 µg/mL Cm) were made from these clones. Both petri dishes and liquid cultures were grown at 37°C.
