Chymotryptase serine protease inhibitor

Functions

A potent, competitive, slow-binding inhibitor of α-, β-, γ-, δ-chymotrypsin, papain and cathepsins B/G (chymotryptase-like serine proteases) Ki=9.36 and 13.1 nM for chymotrypsin and chymase. Cathepsin G Ki=0.15 μM. Consists of a mixture of type A (L-Leu), B (L-Val) and C (L-Ile) forms. Decreases plasma and tissue levels of angiotensin II without lowering mean blood pressure in a hypertensive rat model. Commonly used in lysis buffers to prevent degradation of proteins. Typical working concentration is 6-60 µg/ml.

Application Procedures

First dissolved in DMSO (up to 20 mg/ml), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 1 month.
