SDS-PAGE and Western blotting assays of L. sericata collagenase (MMP-1). (A) SDS-PAGE analysis of recombinant collagenase (MMP-1) in the cell lysate. Lane 1, 48 h after transfection ( The arrows show the target protein); lane 2, 72 h after transfection; lane 3, bacmid control (without target gene); lane 4, normal cells (B) SDS-PAGE analysis of the purified recombinant collagenase (MMP-1) Lane 1, elution 1; lane 2, NTC. (C) Western blotting of the purified recombinant collagenase (MMP-1). Lane 1, elution 1; lane 2, NTC (cell lysate of the transfected cell with bacmid-without target gene)
