Papain, powder


Papain is a sulfhydryl protease from Carica papaya latex. It has a wide specificity and will degrade most protein substrates more extensively than the pancreatic proteases. Papain breaks down the intercellular matrix of cartilage. It also exhibits esterase activity. With some tissues Papain has proved less damaging and more effective than other proteases.

Papain is activated by cystein, sulfide, and sulfite. Stabilizing agents are EDTA, cysteine and dimercaptoethanol.

Papain has a molecular weight of 23,000 daltons and an optimum pH range of 6.0-7.0.

Source: Carica papaya latex
