Anti-BBS9 antibodies are used in the immunodetection of the protein Bardet-Biedl syndrome 9. In humans, the canonical protein has a reported length of 887 amino acid residues and a mass of 99.3 kDa. Its subcellular localization is in the cytoplasm. Up to 7 different isoforms have been reported for this protein. It is widely expressed across many tissue types. BBS9 is known to be involved with cilium assembly and fat cell differentiation. The BBS9 gene has been associated with the disease, Bardet-Biedl syndrome. Synonyms for this target antigen include C18, D1, PTHB1, protein PTHB1, PTH-responsive osteosarcoma B1 protein, and B1. BBS9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of BBS9 antibodies have been mentioned in research publications and have associated citations. Immunofluorescence is a widely used application for these antibodies. ELISA, Western Blot, and Immunohistochemistry are also common applications.
