Universal Protease Substrate

Cat No.
CSUB-0520
Applications
PrincipleBy treatment with proteases, resorufin-labeled peptides are released from resorufin-labeled casein. They cannot be precipitated by trichloroacetic acid. The concentration of these resorufin-labeled peptides in the supernatant is equivalent to the proteolytic activity present.Use Universal Protease Substrate as a general substrate for proteases, and to detect trace protease activities, for example, as a contamination in enzyme preparations. It can be measured spectrophotometrically and fluorimetrically in a homogeneous assay.
