Ac-WEHD-pNA

Colorimetric caspase substrate for caspase-1, -4, -5 and -14.


Colorimetric caspase substrate. Combinatorial studies have found the WEHD sequence to be optimal for clevage of tetrapeptide substrate by caspase-1, caspase-4, caspase-5 and caspase-14. Cleavage of the substrate by a caspase releases pNA, which can be detected by its absorbance at 405nm.


Sequence: Ac-Trp-Glu-His-Asp-pNA (pNA=p-Nitroaniline)
Formulation: Lyophilized.
Peptide Content: 70-90%
Appearance: Yellow powder.
Solubility: Soluble in DMSO. Dilute with buffer, pH 7.5.
Long Term Storage: -20°C
Handling: Keep cool and dry.
Technical Info/Product Notes: λmax of pNA is 400nm.
