Photometric Substrates

Caspase 3: Ac-DEVD-pNA und Z-DEVD-pNA
Caspase 8: Z-IETD-pNA

Fluorimetric Substrates

The 7-amido-4-trifluoromethylcoumarin derivatives have better membrane permeability than the 7-amido-4-methylcoumarin derivatives. Cleavage of R110 peptides by caspases generates strongly fluorescent R110 that can be monitored fluorimetrically at 510-530 nm with excitation of 488 nm. FITC-C6-DEVD-FMK provides a convenient means for sensitive detection of activated caspase-3 in living cells. FITC-DEVD-FMK is cell permeable, nontoxic, and irreversibly binds to activated caspase-3 in apoptotic cells. Z is short for Carboxybenzyl (Cbz).
