Descripción

Descripción general

Soybean trypsin inhibitor (STI) comprises 181 amino acids. It is a monomeric protein corresponding to a molecular weight of 20 kDa and has two disulfide bridges. It belongs to serpins − serine protease inhibitors family.

Especificidad

Soybean trypsin inhibitor is an inhibitor for trypsin, plasmin, and plasma kallikrein. It inhibits trypsin, factor Xa, plasmin, and plasma kallikrein activity in serum-free cell culture media. It does not inhibit metallo-, cysteine, aspartic proteases, or tissue kallikrein (serine proteases).

Aplicación

Trypsin Inhibitor from soybean is used to terminate tissue disaggregation and for subcultivation procedures.

Trypsin Inhibitor has been used:

• in the buffer for hepatocyte isolation
• to inhibit trypsin in Corneal epithelial cells
• to inhibit papain activity while treating hippocampal neural stem cells (NSCs)

Acciones bioquímicas o fisiológicas

Soybean trypsin inhibitor (STI) inhibits myc proto-oncogene protein and is anticarcinogenic. It favors anti-aggregation of platelets and may be a potential protease inhibiting drug. STI inhibits renin and angiotensin.

Soybean trypsin inhibitor is an inhibitor for trypsin, plasmin, and plasma kallikrein. The product is sensitive to heat, alkaline pH, and protein-precipitating compounds.
