Chymotrypsin Substrate I, Colorimetric (trifluoroacetate salt)

Chymotrypsin substrate I, colorimetric is a colorimetric substrate for chymotrypsin. Chymotrypsin binds and hydrolyzes chymotrypsin substrate I, colorimetric to release p-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of chymotrypsin activity.Formal Name: N-(3-carboxy-1-oxopropyl)glycylglycyl-N-(4-nitrophenyl)-L-phenylalaninamide, trifluoroacetate salt.
