Cayman Chemical 7-AmIno-4-methylcoumarIn 250mg
A fluorescent probe for peptide labeling commonly used in the study of proteases; conjugation via its amino group to a peptide substrate results in quenching of the fluorescent signal; upon enzymatic cleavage of the peptide by proteases, AMC is released and its fluorescence can be used to quantify enzyme activity; ex/em = 345/445 nm, respectively
