(A) Expression of PemKSa toxin protein. Lane 1 contains E. coli DE3 total cell lysate protein, Lanes 2, 4, and 6 contains uninduced total cell lysate protein of E. coli DE3. Lanes 3, 5, and 7 contains IPTG induced total cell lysate protein of E. coli DE3. Concentration: Lanes 1, 2, and 3 (50 μg) Lanes 4 and 5 (75 μg) and Lanes 6 and 7 (100 μg), respectively. (B) 100 kDa protein marker (C) Molecular weight corresponding to PemKSa is ~16 kDa. PemKSa protein was purified affinity binding analyzed by 12% SDS-PAGE. Lane 2, 3, and 4 contains purified elute fractions of PemKSa protein.
