Anti-RARRES2 antibodies are used in the immunodetection of the protein retinoic acid receptor responder 2. In humans, the canonical protein has a reported length of 163 amino acid residues and a mass of 18.6 kDa. It has been described to be a secreted protein. RARRES2 is known to be involved with cell differentiation and chemotaxis. Post-translational modifications have been described, including protein cleavage. RARRES2 is also used as a cellular marker for characterizing ependymal cells. Synonyms for this target antigen include TIG2, retinoic acid receptor responder protein 2, RAR-responsive protein TIG2, chemerin, retinoic acid receptor responder (tazarotene induced) 2, and HP10433. RARRES2 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Over 70 citations in the literature describe the use of RARRES2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
