Anti-OR4D9 antibodies are used in the immunodetection of the protein olfactory receptor family 4 subfamily D member 9. In humans, the canonical protein has a reported length of 314 amino acid residues and a mass of 35.7 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 OR11-253, olfactory receptor, family 4, subfamily D, member 9 pseudogene, and olfactory receptor 4D9. Western Blot is a widely used application for the OR4D9 antibodies listed below. In addition, ELISA is also a common application.
