Anti-OR4B1 antibodies are used in the immunodetection of the protein olfactory receptor family 4 subfamily B member 1. In humans, the canonical protein has a reported length of 309 amino acid residues and a mass of 34.5 kDa. Its subcellular localization is in the cell membrane. It is a member of the G-protein coupled receptor 1 protein family. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include olfactory receptor 4B1 and olfactory receptor OR11-106. OR4B1 gene orthologs have been reported in the mouse and chimpanzee species. Immunofluorescence is a widely used application for the OR4B1 antibodies listed below. In addition, ELISA is also a common application.
