General description

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.

Biochem/physiol Actions

Inhibitor Type: Protease Inhibitors

Physical form

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.

Preparation Note

Maintain lyophilized material at -20ºC for up to one year. Store reconstituted product in aliquots at -20ºC for up to 3-4 weeks. Do not thaw and refreeze.
