Ac-LETD-AFC is a caspase-8 fluorogenic substrate. Ac-LETD-AFC can measure caspase-8 fluorogenic activity and can be used for the research of cancer cell apoptosis and oxidative stress metabolism^[1].

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Caspase activity assay^[1]:
1. Incubate the cells according to your normal protocol.
2. Wash cells once with PBS and centrifugate.
3. Resuspend cells in PBS at a concentration of 1× 10⁷ cells/mL.
4. Prepare the standard reaction buffer which includ 100 μM caspase-8 substrate AC-LETD-AFC. Prepare correspounding standard reaction buffer according to your protocol.
5. Add 15 ul of the cells suspension to a microplate, and mixed with the appropriate peptide substrate dissolved in a standard reaction buffer.
6. Measure substrate cleavage with a microplate reader with excitation wavelength of 360 nm and emission at 460 nm.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
