Following is the molecular structure of Ac-DEVD-AMC (CAS NO.169332-61-0):

 

The Ac-DEVD-AMC (CAS NO.169332-61-0) substrate was made on a peptide synthesizer and purified according to standard protocols: purity ≥ 98%, MW=675 Daltons.
The Ac-DEVD-AMC (CAS NO.169332-61-0) substrate is routinely 800 evaluated in protease assays using apoptotic and non-apoptotic cell lysates or purified, active Caspase-3. Ac-DEVD-600 AMC has been previously reported to have linear Michaelis-Menton kinetics with a Km of 10 μM for Caspase-3.
The Ac-DEVD-AMC (CAS NO.169332-61-0) fluorogenic substrate is designed to be used in protease assays, like those described in the literature by Mashima et al and Nicholson et al. When Ac-DEVD-AMC is treated with pure and active Caspase-3 or apoptotic cell lysates, AMC is released. AMC release is monitored in a spectrofluorometer at an excitation wavelength of 380 nm and an emission wavelength range of 430-460 nm. Apoptotic cell lysates containing active Caspase-3 yield a considerable emission as compared to non-apoptotic cell lysates. Apoptosis can be induced by a number of mechanisms. For each protease assay, we typically use a 1 ml reaction buffer [20 mM HEPES (pH 7.5), 10% glycerol, 2 mM DTT], 20 μM.

Safety Information of Ac-DEVD-AMC (CAS NO.169332-61-0):
WGK Germany: 3

 Ac-DEVD-AMC (CAS NO.169332-61-0) is a synthetic tetrapeptide fluorogenic substrate for Caspase-3 (CPP32) and contains the amino acid sequence of the PARP cleavage site at Asp-216. The tetrapeptide substrate can be used to identify and quantify the Caspase-3 activity in apoptotic cells. Caspase-3
cleaves the tetrapeptide between D and AMC, thus releasing the fluorogenic AMC, which can be quantified in a spectrofluorometer. The substrate can also be used to study the inhibition of Caspase-3 by the tetrapeptide aldehyde, Ac-DEVD-CHO or any other inhibitor of Caspase-3.
