Inhibits the lysosomal proteinase cathepsin B, and the soluble Ca2+-activated proteinase. Many young plant tissues express a chomostatin-sensitive serine protease. Chymostatin is a strong inhibitor of many proteases, including chymotrypsin, papain, chymot

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Product Description
Chymostatin is a bioactive peptide protease inhibitor that contains chymostatin A as a major form. The compound specifically inhibits chymotrypsin (CTR) (ID50 = 150 ηg/ml), papain (ID50 = 7.5 μg/ml), and cathepsin G along with most cysteine proteases such as cathepsin A, B, H, and L. The compound has been noted as a strong inhibitor of cathepsins A, B, and C. Chymostatin at an effective concentration of 10 to 100 μM weakly inhibits human leukocyte Elastase-1. In rat muscle homogenates chymostatin inhibited the protease cathepsin B and other soluble Ca2+ activated proteases. In the same study, chymostatin decreased protein break down by 20-40% without inhibiting protein production.
