Suc-LLVY-[AMC] – Fluorescent Peptides

Fluorogenic substrate peptide of the 20S proteasome. In its intact state this peptide is non-fluorescent, however when aminomethylcoumarin (AMC) is released upon hydrolysation, fluorescence can be detected. This peptide is therefore a useful tool for analysing the activity of the 20S proteasome as well as other chymotrypsin-like proteases and calpains. This peptide is also a substrate for chymase, papain, carboxypeptidase Y, proteinase yscE (kexin) and ingensin. AMC is a fluorescent dye with excitation maxima at around 360 nm and emission maxima at around 450 nm. AMC can be excited with a mercury lamp and observed using a UV filter set.
