Resorufin Acetate

Resorufin acetate is a fluorometric probe that acts as a substrate for cytosolic aldehyde dehydrogenase (ALDH1A1) esterase activity. It is also a useful substrate for chymotrypsin. Upon enzymatic cleavage, the resorufin anion displays red fluorescence (ex/em maxima = 570/580 nm, respectively).Formal Name: 7-(acetyloxy)-3H-phenoxazin-3-one. CAS Number: 1152-14-3.
