Description

Caspase 8, also known as FLICE, MACH and Mch5 is self-activated or activated in response to granzyme B cleavage. Caspase 8 specifically recognizes IETD. Activated caspase 8 can not only cleave PARP, but also participate in the activation of other ICE family proteases, such as caspase 3 and caspase 7. This caspase 8 activity assay kit is based on caspase 8 that can catalyze the substrate Ac-IETD-pNA to generate yellow pNA (p-Nitroaniline). The pNA has a strong absorption near 405 nm, The activity of caspase 8 can be calculated by determining the absorbance at 405 nm.

Background: Caspase-8

Caspase 8 (CASP8) is a member of the cysteine-aspartic acid protease (caspase) family that is involved in the execution-phase of cell apoptosis. The sequential activation of caspases plays a central role in the execution-phase of cell apoptosis, and Caspase 8 is the most upstream protease in the the caspase activation cascade.

Caspase 8 is expressed as an inactive proenzyme which then undergos proteolytic processing by upstream caspases, to form an active (cleaved) caspase 8 form.

Caspase 8 antibodies are important tools for apoptosis studies and research on the caspase family mediated apoptosis signaling pathway.

FAQs for Caspase-8 Activity Assay Kit (Colorimetric)

Showing  1 - 1 of 1 FAQ Showing All

  • Q: May we ask the MW difference between the active form and the proform of Caspase 8 while performing WB?

    A: In treated cells induced to undergo apoptosis, caspase-8 migrates as a 55/53 kDa (pro-form), 41/42 kDa (a cleaved/active or intermediate form), and 18 kDa (active form). The proform (55/53 kDa) is still seen in treated cells because not all cells undergo apoptosis at once.
