Native Human Cathepsin B

• Cat.No.: CTSB-1647H
• Product Overview: Native Human Cathepsin B was purified from Human Liver.

Specification

• Description: Cathepsin B , a cysteine proteinase, is located in lysosomes and is involved in tissue degradation and restructuring. Specifically, cathepsin B is believed to be involved in the intracellular digestion of extracellular proteins taken up by endocytosis.
• Source: Human Liver
• Species: Human
• Form: Frozen in 50 mM Na Acetate, pH 5.0, with 1 mM EDTA.
