Goal B: Characterization of λ Lysis cassette
Introduction
To characterize our lysis device quantitatively, we regulate the gene expression of lysiscassette by a lactose promoter, R0011, which we characterized quantitatively by RPU in GoalA. To repress the basal expression of lysiscasette without IPTG as possible, we used pSB4K5, a low copy vector, as a plasmid backbone and used KRX as a host cell. Needless to say, we characterized R0011 in the same experimental condition.
We grew these cultures to saturation at 37 degrees Celsius in supplemented M9 media, and then dillute with the same media 100 fold, growing to mid-log , and split 3ml into falcon tubes. A range of concentrations of IPTG was added to these cultures, and they were then incubated at 37 degrees . and the absorbance at 550nm was measured every 30 min ｗｉｔｈ きかい
