Chymostatin. M.W. 604.92
Mixture of types A, B and C. Inhibits Chymotrypsin-like serine proteases including alpha, beta, gamma and delta chymotrtrypsins.
Sequence:
[(S)-1-Carboxy-2-Phenylethyl]-Carbamoyl-a-[2-Iminohexahydro-4(S)-Pyrimidyl]-(S)-Glycyl-X-Phenylalaninal
X: L-Leu (type A), L-Ile (type B), L-Val (type C)
Working concentrations 10-100μM.
Stable for several hours. Soluble in DMSO and glacial acetic acid. Solutions are stable for a month at -20ºC.
5mg/825 microliters in DMSO = 10mM solution.
Dilute 1:100 for 100μM working solution.

生化／生理作用
Inhibitor Type: Protease Inhibitors
外觀
Lyophilized. Dissolve in dimethylsulfoxide (DMSO). After powder is thoroughly dissolved, dilute the DMSO solution with 0.9% NaCl. The concentration of DMSO should be maintained at 10% or higher. Otherwise chymostatin may precipitate from the solution.
Example: Reconstitute 1 mg of chymostatin with 1.65 mL of DMSO. Then add 14.85 mL of 0.9% NaCl. This furnishes a 10-4 M solution. No preservatives added.
