FADD (Fas-Associated Death Domain Protein, MORT1)

Fas-associated death domain (FADD, also known as MORT1) is an important apoptosis adapter molecule involved in the Fas-mediated cell death pathway. FADD associates with the intracellular domain of FAS (CD95/APO-1) through their respective C-terminal death domains (DD). The N-terminal region of FADD contains a death effectors domain (DED) which recruits and binds cytosolic proteins such as FLICE/caspase-8. The subsequent activation of FLICE by proteolytic cleavage leads to the activation of the caspase-mediated (ICE-related proteases) apoptotic cascade. Overexpression of FADD induces apoptosis which is inhibited by CrmA, a specific inhibitor of the interleukin-1beta-converting enzyme. FADD has also been shown under certain circumstances to promote cell survival and proliferation.1-6\n\nApplications: \nSuitable for use in ELISA, Western Blotting. Other applications not tested.\n\nRecommended Dilution:\nWestern Blotting: 1:500-1:1000\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.\n\nHybridoma: \nMouse FO myeloma cells with spleen cells from BALB/c mice immunized with a recombinant human FADD protein.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20 degrees C or colder. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
