Anti-FAM171B antibodies are used in the immunodetection of the protein family with sequence similarity 171 member B. In humans, the canonical protein has a reported length of 826 amino acid residues and a mass of 92.2 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the FAM171 protein family. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include protein FAM171B. FAM171B gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Some FAM171B antibodies may have been used in research and have associated citations. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
