Nom du produit

Trypsin-chymotrypsin inhibitor from Glycine max (soybean), lyophilized powder

Source biologique

Glycine max (soybean)

Niveau de qualité

Forme

lyophilized powder

Composition

Protein, 70-90% biuret

Température de stockage

2-8°C

Description générale

Highly cross-linked with seven disulfide bridges, Bowman-Birk inhibitor has spatially distinct domains for trypsin and chymotrypsin inhibition.
Trypsin-chymotrypsin inhibitor belongs to the family of plant protease inhibitors. It is mainly found in the legume (Fabaceae) and cereal (Poaceae) families. Trypsin-chymotrypsin inhibitor consists of many internal disulfide bonds between conserved Cys residues, which maintains structural stability and active conformation of the inhibitory loops.[1] Trypsin-chymotrypsin has anticarcinogenic properties.[2]

Application

Bowman Birk protease inhibitor prevents radiation-induced carcinogenesis by a reduction of incorrect DNA repairs, resulting in a reduced amount of dicentric chromosomes.
Trypsin-chymotrypsin inhibitor from Glycine max (soybean) has been used for flow cytometric separase activity assay.[3] It has also been used to inhibit trypsin and chymotrypsin for in vitro gastrointestinal (GI) digestion studies.[4]

Définition de l'unité

One trypsin unit = ΔA253 of 0.001 per min with BAEE as substrate at pH 7.6 at 25 °C. Reaction volume = 3.2 mL (1 cm light path).

Forme physique

Lyophilized powder containing phosphate buffer salts, pH 7.6

Remarque sur l'analyse

1 mg protein will inhibit ≥0.5 mg trypsin with activity of ~10,000 BAEE units per mg protein or ≥1.0 mg chymotrypsin with activity of ~40 BTEE units per mg protein.

Bowman-Birk inhibitors (BBI) from soybean and related proteins are naturally occurring protease inhibitors with potential health-promoting properties within the gastrointestinal tract. In this work, we have investigated the effects of soybean BBI proteins on HT29 colon adenocarcinoma cells, compared with
