Reactivity Key:  H=Human
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

Bid (3C5) Mouse mAb recognizes endogenous levels of total Bid protein. This antibody does not cross-react with endogenous levels of tBid during apoptosis.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a recombinant protein specific to the full-length sequence of human Bid protein.

Background

Bid is a pro-apoptotic “BH3 domain-only” member of the Bcl-2 family originally discovered to interact with both the anti-apoptotic family member Bcl-2 and the pro-apoptotic protein Bax (1). Bid is normally localized in the cytosolic fraction of cells as an inactive precursor and is cleaved at Asp60 by caspase-8 during Fas signaling, leading to translocation of the carboxyl terminal p15 fragment (tBid) to the mitochondrial outer membrane (2-4). Translocation of Bid is associated with release of cytochrome c from the mitochondria, leading to complex formation with Apaf-1 and caspase-9 and resulting in caspase-9 activation (5-7). Thus, Bid relays an apoptotic signal from the cell surface to the mitochondria triggering caspase activation (8,9).
