BCDA is a chromogenic substrate of esterase used to detect the activity of esterase.

3-Cyano-7-ethoxycoumarin is a fluorogenic substrate suitable for the continuous determination of cytochrome P450 mixed-function monooxygenases. It is a fluorescent probe useful in microsomal dealkylase studies.

Ac-Lys-AMC (Hexanamide), also termed MAL, is a fluorescent substrate for histone deacetylase HDACs.

Fluorescein di(β-D-galactopyranoside) is a fluorogenic substrate for β-galactosidase (λex=485 nm, λem=535 nm).

ADHP is a fluorogenic peroxidase substrate (λex=530 nm, λem=590 nm).

D-Luciferin sodium salt is the substrate of luciferases that catalyze the production of light in bioluminescent insects.

BCIP(BCIP p-toluidine salt; X-phosphate p-toluidine salt) is an artificial chromogenic substrate used for the sensitive colorimetric detection of alkaline phosphatase activity.
