Molecular Weight: 664.77Salt Form: TFAPurity: >96%Sequence (3-letter): Z-Ala-Lys-Arg-AMCSequence (1-letter): Z-AKR-AMCStorage: -20 °C or belowZ-Ala-Lys-Arg-AMC is a fluorogenic substrate for IRCM-Serine Protease 1. Activity is quantified by release of free fluorescent 7-amino-4-methylcoumarin (AMC) which excites at 360-380 nm and emits at 440-460 nm.Reference: J.A. Cromlish et al.
