Anti-BEST2 antibodies are used in the immunodetection of the protein bestrophin 2. In humans, the canonical protein has a reported length of 509 amino acid residues and a mass of 57.1 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in the colon and rectum. A member of the Anion channel-forming bestrophin (TC 1.A.46) protein family, BEST2 is known to be involved with the sensory perception of smell. Synonyms for this target antigen include VMD2-like gene 1, vitelliform macular dystrophy 2-like 1, vitelliform macular dystrophy 2-like protein 1, and VMD2L1. BEST2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some BEST2 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
