Anti-HTR6 antibodies are used in the immunodetection of the protein 5-hydroxytryptamine receptor 6. In humans, the canonical protein has a reported length of 440 amino acid residues and a mass of 47 kDa. Its subcellular localization is in the cell membrane. It is reported to be expressed in several human brain regions, most prominently in the caudate nucleus. A member of the G-protein coupled receptor 1 protein family, HTR6 is known to be involved with chemical synaptic transmission. Synonyms for this target antigen include 5-HT6R, 5-hydroxytryptamine (serotonin) receptor 6, G protein-coupled, serotonin receptor 6, and 5-HT6. HTR6 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of HTR6 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
