Applications of BBa_K358019

Using this part, we checked the function of SRRz gene.

Firstly, we constructed this part on low copy plasmid, pSB4K5, and transformed into KRX. It is necessary to repress the lactose promoter and avoid the disadvantage of cell lysis.

Secondly, we cultured E.coli on M9-Km 30C/overnight.


Experiment 1:

Then, diluted the sample and added IPTG as the inducer. We measured A550 at each time.


Experiment 2:

We added IPTG, not dilute the sample. We measured A550 at each time.


Finally,


Culture condition:

We also performed some experiences at 37C culture condition. However, in a few experiment, unexpected mutations on lactose promoter had occurred and the promoter wouldn't work in the end. We done the sequencing on this sample (see here,).
