Colony PCR of 8 clones containing fragment 1 and 2 (dCas9 Nm GFP 10) in pSB1C3

Mahnaz

Transformed cells on 26th august which had been grown overnight were used for colony PCR. For that purpose, 8 clones containing dCas9 NM - GFP 10 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

PCR was performed as follow:

Primers used were:

After amplification, 3 µL of each PCR products and 5 µL of DNA ladder were placed in wells and migrated at 100V during 30 min.

PCR products expected were :

Result of migration

The result shows that Gibson assembly did not work out.
