plasmid extraction : pGEMTeasy + chromoprotein

by Laetitia

We used the bacteria containing pGEMTeasy + chromoprotein launched by Melanie sunday the 24th for the plasmid extraction, 6 independent cultures which come from 6 independent colonies.

We made a stock of bacteria for each sample (x6).

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

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 5 μl
Fast Digest buffer 10X 1μl
XbaI 0.5μl
PstI 0.5μl
H20 3μl

Results : the samples 3, 4 and 6 seems to contain the chromoprotein gene (two bands)

Bacterial culture of DH5a containing pGEMTeasy + chromprotein

by Laetitia

We launched 6 cultures in 5mL LB + Ampi (1/1000) - 37°C at night . The bacteria come from the stock made before the plasmid extraction
