Caspase 9 Substrate 1, chromogenic

• Supplier: Creative Peptides
• Product #: A55003
• MolecularWeight: 674.7
• Sequence:
  • One Letter Code: Ac-LEHD-pNA
  • Three Letter Code: Ac-Leu-Glu-His-Asp-pNA
• Storage: -20°C desiccated and protected from light
• Explanation: pNA (4-nitroaniline)-derived caspase substrates are widely used for the colorimetric detection of various caspase activities. Cleavage of pNA peptides by caspases generates pNA that is monitored colorimetrically at ~405 nm. pNA has maximum absorption around 408 nm.
