the enzyme extracted from tissues was proven to be lysosomal cathepsin b by sds gel electrophoresis in the use of human type i and type iii collagen . alpha-n-benzoyl-dl-arginine-2-naphthylamide hcl ( bana ) was supposed to be specific for cathepsin b , and so bana-hydrolase activity was measured as collagen-degrading cathepsin .
