Anti-FAIM antibodies are used in the immunodetection of the protein Fas apoptotic inhibitory molecule. In humans, the canonical protein has a reported length of 179 amino acid residues and a mass of 20.2 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the FAIM1 protein family, FAIM is reported to play a role as an inducible effector molecule that mediates Fas resistance produced by surface Ig engagement in B cells. Synonyms for this target antigen include FAIM1 and fas apoptotic inhibitory molecule 1. FAIM gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of FAIM antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
