Usage and Biology

The lysis gene from colicin-producing strains of bacteria encodes the lysis protein which can cause the host cell to lyze as long as the protein is activated. On the basic of its biological function, we can use lysis gene to break our engineering E.coli and release the interior cell contents when it's time to extract our product-shRNA by adding a Tryptophan attenuator between a RBS and lysis gene

We transformed the expression vector into HT115 (DE3) E.coli by heat-shock method, and they were cultured in 1 LB liquid medium to exact exponential phase. Afterwards, we started a cell growth curve experiment of our engineering E.coli(illustrated with Fig.1)
