BD, 556402, Purified Mouse Anti-Human FADD A66-2

FADD is a molecule involved in the Fas-mediated cell death pathway. Apoptosis is induced when Fas ligand or agonistic Fas antibodies bind to the Fas receptor, and trigger the activation of a cell death signaling pathway. Induction of Fas-mediated apoptosis requires a conserved cytoplasmic motif, referred to as the death domain, that is present in the C-terminal end of Fas. FADD also contains a death domain, and Fas and FADD bind to each other through their respective death domains. Death domains are thought to act as adaptor proteins by linking Fas and other members of the tumor necrosis factor receptor (TNFR) superfamily to downstream signaling pathways. Overexpression of FADD in vitro leads to cell death suggesting that FADD, like FAS, is an apoptosis-inducing protein. The N-terminal, but not the C-terminal death domain, is required for apoptosis induced by FADD overexpression. It is thought that the amino-terminal region of FADD functions by binding to caspase-3 and thereby linking signals from the cell surface to an apoptopic protease cascade. FADD has a calculated molecular weight of 24 kDa and migrates at a molecular weight of ~27 kDa in SDS/PAGE.
Clone A66-2 can be used for western blot analysis (1-2 µg/ml). Other reported applications not routinely tested at BD Biosciences include immunoprecipitation (1-2 µg/1x10^6 cells). Daudi B lymphoma cells (ATCC CCL-213) are suggested as a positive control.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
