Anti-TAS2R38 antibodies are used in the immunodetection of the protein taste 2 receptor member 38. In humans, the canonical protein has a reported length of 333 amino acid residues and a mass of 37.9 kDa. Its subcellular localization is in the membrane. It is reported to be expressed in subsets of taste receptor cells of the tongue and exclusively in gustducin-positive cells. A member of the G-protein coupled receptor T2R protein family, TAS2R38 is a known receptor that may play a role in the perception of bitterness and is gustducin-linked. Synonyms for this target antigen include T2R38, T2R61, THIOT, taste receptor type 2 member 38, PTC bitter taste receptor, and PTC. TAS2R38 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of TAS2R38 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
