SDS-PAGE analysis of purified cysteine protease of Taenia solium metacestode (A) and gelatinolysis by the purified cysteine protease (B). The gel was analyzed on 7.5-15% gradient gel. Mr, standard marker proteins. Panel A, lanes a, crude extracts; b, partially purified cysteine protease through Mono Q column; and c, purified cysteine protease. Panel B, lanes a, crude extracts; b, purified cysteine protease without inhibitor; and c, purified cysteine protease with respective inhibitor, IAA. Proteolytic activity was shown on white area on gelatin gel (white arrow).
