Ac-VEID-pNA (trifluoroacetate salt)

Ac-VEID-pNA is a substrate for caspase-6. Caspase-6 binds to and cleaves the Val-Glu-Ile-Asp (VEID) peptide sequence to release p-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of enzyme activity.Formal Name: N-acetyl-L-valyl-L-alpha-glutamyl-L-isoleucyl-N-(4-nitrophenyl)-L-alpha-asparagine, trifluoroacetate salt.
