Lab work

plasmid extraction : pGEMTeasy + chromoprotein

by Laetitia

We used the bacteria containing pGEMTeasy + chromoprotein launched by Laetitia monday the 25th for the plasmid extraction, 6 independent cultures which come from the 6 stocks made yesterday.

To extract the plasmid, we used the plasmid DNA purification kit (Macherey-Nagel). Protocol for low copy plasmid.

Digestion of pGEMTeasy+chromoproteinby XbaI and PstI

by Laetitia

The goal is to check the presence of the insert inside the plasmid. We digest the 6 samples of purified plasmid.

component volume
Plasmid 10 μl
Fast Digest buffer 10X 1,5 μl
XbaI 0.5μl
PstI 0.5μl
H20 2,5 μl

1h at 37°C

D - Lemon Scent

Streaking of colonies containing BBa_K762100+pGEMTeasy

Due to yesterday's strange results, we conduct 30 streakings in a petri dish: 28 white colonies and 2 blue colonies.
