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,

+We also tried to culture at 37C, but, in some experiences, an unexpected mutation had occurred on lactose promoter and the promoter wouldn't work in the end.
+|- We performed sequencing to the sample(see here,).
