Description

General description

A useful substrate for colorimetric or fluorometric assay of cathepsin D activity. Cathepsin D hydrolyzes the Phe-Phe bond. Dipeptidyl aminopeptidase II is required to free the 4-methoxy-β-naphthylamine (4MβNA). Excitation max: ~345 nm; emission max: ~425 nm.

Useful as a substrate for the determination of cathepsin D activity. Suitable for either colorimetric or fluorometric assay. Cathepsin D hydrolyzes the Phe-Phe bond. Requires dipeptidyl aminopeptidase II to free 4-methoxy-β-naphthylamine (4MeOβNA).
