Resorufin butyrate

Resorufin butyrate is a fluorogenic substrate for triglyceride lipases. It is also a substrate for cholinesterase. Upon enzymatic cleavage by triglyceride lipases or cholinesterase, resorufin is released and can be used to quantify triglyceride lipase or cholinesterase activity. Resorufin displays excitation/emission maxima of 570/580 nm, respectively.Formal Name: 3-oxo-3H-phenoxazin-7-yl-butanoic acid ester. CAS Number: 15585-42-9. Molecular Formula: C16H13NO4.
