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

D1 - D2 - D3 - D4 - D5 - D6 - T - L
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.
