Expression of endolysin XFII. A Bacteriophage plaques of XFII diluted several times. B SDS-PAGE profiles of extracts of E. coli BL21 expressing endolysin XFII. Lanes: M, protein ladder; lane 1, the supernatant of bacterial lysate of the native protein; lane 2, the supernatant of the culture medium of the native protein; lane 3, the XFII endolysin (25.4 kDa) was purified by Ni–NTA affinity chromatography
