Anti-TAS2R19 antibodies are used in the immunodetection of the protein taste 2 receptor member 19. In humans, the canonical protein has a reported length of 299 amino acid residues and a mass of 33.9 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, TAS2R19 is a known receptor that may play a role in the perception of bitterness and is gustducin-linked. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include taste receptor, type 2, member 19, taste receptor, type 2, member 23, taste receptor, type 2, member 48, and taste receptor type 2 member 19. Western Blot is a widely used application for the TAS2R19 antibodies listed below. In addition, ELISA is also a common application.
