Anti-OR5-40 antibodies enable researchers to detect and measure the OR5-40 antigen in biological samples. This target is a reported synonym of the OR2B6 gene, which encodes olfactory receptor family 2 subfamily B member 6. The human version of OR5-40 has a canonical amino acid length of 313 residues and a protein mass of 35.4 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include OR2B1, OR2B1P, and OR2B5.
