Anti-HNRNPR antibodies are used in the immunodetection of the protein heterogeneous nuclear ribonucleoprotein R. In humans, the canonical protein has a reported length of 633 amino acid residues and a mass of 70.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. HNRNPR is known to be a component of ribonucleosomes, which are complexes of at least 20 other different heterogeneous nuclear ribonucleoproteins (hnRNP). Synonyms for this target antigen include HNRPR and NEDDFSB. HNRNPR gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. A number of HNRNPR antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
