In 2022, ZJU-China iGEM team has characterized the output of this part in a novel chassis E. coli BL21(DE3). The result was documented in the experience page and the main page of (BBa_K302018).
Contribution from iGEM2022 ZJU-China
The sequence of (BBa_K302018) was synthesized and cloned into the PHY-plasmid to obtain the recombinant expression vector
We first tested the inhibitory concentration of subtilisin by zone of inhibition experiment, using BL21 transformed by PHY-Immunity plasmid or PHY-Empty plasmid as control. The concentration of subtilisin were 100mg/ml, 50mg/ml, 25mg/ml, 12.5mg/ml.
Then, we prepared normal LB culture plates with different concentration of subtilisin, including 0.1mg/ml, 0.2mg/ml, 1mg/ml and 10mg/ml, in individual dishes. Then we inoculated BL21 transformed by immunity plasmid or PHY-empty plasmid as control in the plates. <p>Results：For the immunity group, some colonies grew on the surface of the media with 1mg/ml subtilisin, while the control group didn’t. This suggested that the PHY-Immunity plasmid worked well in BL21.
