Labwork

Contruction of the fusion protein

By Hv

We can see that the blue colonies of E.coli are not blue in a simple petri dish with ampicillin. It's a fail. So, to figure our problem we decided to do a sequencing of our plasmids.

We chose 6 colonies from an Xgal-IPTG petri dish:

- 1 completely blue

- 2 blue with a white ring around the blue

- 3 white colony

PS: we found that there is 2 types of blue colonies: completely blue and blue with a white ring around the blue)

We first did a liquid culture in 5 mL of LB.

pPPS5

the photo in the same as previously: We saw a band but we will check another time by PCR to be sure.

pPS3 and pPS4

Plasmid extraction using the plasmid DNA extraction kit and electrophoresis:

Extraction, pPS3 pPS4 0209.jpg

We conclude that we have done a good manipulation.

Limonene synthase PCR

As we saw that we don't have anything for LS, We try to do other PCR from the Biobrick (BBA762100). We use two enzyme: Dream taq and Vent taq

component volume
H2O 42μl
buffer 5μl
dNTPs 1μl
iPS66 1μl
iPS67 1μl
DNA 0.5μl
enzyme 0.5μl

Tubes were placed in PCR machine with the following parameters.

To have more plasmid We do some bacteria culture (pPS5)
