Anti-OPN1SW antibodies are used in the immunodetection of the protein opsin 1, short wave sensitive. In humans, the canonical protein has a reported length of 348 amino acid residues and a mass of 39.1 kDa. Its subcellular localization is in the cell membrane and cytoplasm. It is notably expressed in the retina and testis. A member of the G-protein coupled receptor 1 protein family, OPN1SW is known to be involved with GPCR signaling pathways. The OPN1SW gene has been associated with the disease, Tritan color blindness. Synonyms for this target antigen include BOP, short-wave-sensitive opsin 1, blue cone photoreceptor pigment, blue-sensitive opsin, and BCP. OPN1SW gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of OPN1SW 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.
