Anti-OR5B21 antibodies are used in the immunodetection of the protein olfactory receptor family 5 subfamily B member 21. In humans, the canonical protein has a reported length of 309 amino acid residues and a mass of 34.2 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, OR5B21 is known to be involved with GPCR signaling pathways and the sensory perception of smell. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include olfactory receptor 5B21. OR5B21 gene orthologs have been reported in the mouse, rat and chimpanzee species. Indicated applications for OR5B21 antibodies listed below include ELISA and Western Blot.
