Anti-PTH2 antibodies are used in the immunodetection of the protein parathyroid hormone 2. In humans, the canonical protein has a reported length of 100 amino acid residues and a mass of 11.2 kDa. It has been described to be a secreted protein. It is reported to be highly expressed in fetal and adult brain, cerebellum and trachea. A member of the Parathyroid hormone protein family, PTH2 is reported to play a role as a potent and selective agonist of PTH2R resulting in adenyl cyclase activation and intracellular calcium levels elevation. Synonyms for this target antigen include tuberoinfundibular peptide of 39 residues and tuberoinfundibular 39 residue protein. PTH2 gene orthologs have been reported in the mouse, rat, bovine, zebrafish and chimpanzee species. Immunocytochemistry is the most common application for the PTH2 antibodies listed below. ELISA, Western Blot, and Immunofluorescence are also common applications.
