Suc-AAP-Abu-pNA (trifluoroacetate salt)

Suc-AAP-Abu-pNA is a chromogenic peptide substrate for pancreatic elastase. It is cleaved by elastase to release p-nitroalinide (p-NA), which can be quantified by colorimetric detection at 405 nm as a measure of enzyme activity.Formal Name: N-(3-carboxy-1-oxopropyl)-L-alanyl-L-alanyl-L-prolyl-N-(4-nitrophenyl)-L-2-amino-butanamide, trifluoroacetate salt.
