Receptor for TNFSF6/FASLG. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. FAS-mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. The secreted isoforms 2 to 6 block apoptosis (in vitro).

The stated application concentrations are suggested starting points. Titration of the Fas antibody may be required due to differences in protocols and secondary/substrate sensitivity.

A human recombinant protein was used as the immunogen for this Fas antibody.

Store the Fas antibody at -20oC.
