CATHEPSIN B, BOVINE SPLEEN

Cathepsin B, Bovine Spleen
Native cathepsin B from bovine spleen, purified by affinity chromatography. Cathepsin B, one of the most investigated lysosomal cysteine proteinases, is widely distributed in a variety of tissues. The enzyme exists in a two-polypeptide chain form consisting of an H-chain of 22 - 23 kDa and an L-chain of 5 kDa. Cathepsin B is shown to facilitate tumor invasion by dissolving extracellular barriers.
