Expression and identification of the recombinant toxin rCCK96-104PE38 in Escherichia coli (E. coli). ((a) expression of recombinant protein rCCK96-104PE38 in E. coli; (b) expression of the recombinant protein rCCK96-104PE38 identified by the Western Blot). Note: M: maker; 1: 0.1 mM IPTG-induced BL21 (DE3) (PET28a) empty carrier protein; 2: 0.1 mM IPTG-induced BL21 (DE3) (pET28a-rCCK96-104PE38) protein; 3: the E. coli samples without IPTG induction; 4: the E. coli samples induced by IPTG.
