Anti-OR19-18 antibodies enable researchers to detect and measure the OR19-18 antigen in biological samples. This target is a reported synonym of the OR7C2 gene, which encodes olfactory receptor family 7 subfamily C member 2. This protein is known to function in signal transduction pathways, among other biological roles. The human version of OR19-18 has a canonical amino acid length of 319 residues and a protein mass of 35.3 kilodaltons. It is reported to be localized in the cell membrane of cells. OR19-18 is a member of the G-protein coupled receptor 1 protein family.
