Chlorotoxin

A fluorogenic peptide substrate that can be used to monitor 20S Immunoproteasome activity, which is excited at 345 nm and emits at 445 nm. This substrate is specific to the immunoproteasome, and is not hydrolyzed efficiently by the constitutive proteasome.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
