Molecular Weight: 661.26 Salt Form: N/A Purity: >96% Sequence (3-letter): Ac-Val-Glu-Thr-Asp-AMC Sequence (1-letter): Ac-VETD-AMC Storage: -20 ?C or below Ac-Val-Glu-Thr-Asp-AMC is a fluorogenic substrate for Caspase 8. Caspase 8 is a cysteine protease involved in apoptosis induced by Fas and other stimuli. 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.
