The monoclonal antibody 1H10 recognizes human Caspase-8 also known as FLICE and MACH, a member of the cysteine-requiring aspartate protease family. Caspase-8 is an upstream caspase responsible for Fas and TNF-alpha mediated apoptosis. After activation of the Fas or TNF receptors by their ligands, the adaptor molecule FADD binds to the receptor and recruits caspase-8 to the membrane. The formation of this complex induces the cleavage and activation of caspase-8. The active form of caspase-8, made of a heterotetramer of p18 and p10, is released in the cytoplasm and activates downstream apoptotic proteases (caspase-3, -4, -6, -7, -9 and -10). Several (gt 8) isoforms have been identified: 3 different pro-forms called Caspase-8a (55kDA), Caspase-8b (53kDa), and Caspase-8L which is procaspase-8 with an additional N-terminal extension of 59 aa. The 1H10 antibody recognizes the p55 and p53 proforms in addition to the p43 and p18 cleaved forms. Under reducing conditions, an additional band (possibly non-specific) around 35kDa may be present. Under nonreducing conditions, this band is absent.

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