Ac-Leu-Arg-AMC is a fluorogenic peptide substrate.

p-Nitrophenyl phosphorylcholine (4-Nitrophenylphosphorylcholine) is a chromogenic Phospholipase C substrate. Phospholipase C hydrolyzes p-Nitrophenyl phosphorylcholine to release p-nitrophenol, a yellow chromophore. p-Nitrophenyl phosphorylcholine is used to determine the phospholipase C production of Pseudomonas aeruginosa. It also applies to studies related to Pseudomonas aeruginosa infection.

C6 NBD galactosylceramide is an active derivative of galactosylceramide that is tagged with fluorescent C6 nitrobenzoxadiazole (C6 NBD).
