Molecular Weight: 674.28 Salt Form: TFA Purity: >96% Sequence (3-letter): Ac-Leu-Glu-His-Asp-pNA Sequence (1-letter): Ac-LEHD-pNA Storage: -20 ?C or below Ac-Leu-Glu-His-Asp-pNA is a colorimetric substrate for Caspase 9. Caspase 9 is a cysteine protease which acts as an initiating enzyme in apoptosis pathways. It activates Caspases 3, 6, & 7. Activity is quantified by the release of p-nitroaniline which is measured by absorbance at 405 nm.
