Anti-QRICH2 antibodies are used in the immunodetection of the protein glutamine rich 2. In humans, the canonical protein has a reported length of 1663 amino acid residues and a mass of 180.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in the sperm. QRICH2 is known to have an essential role in the formation of sperm flagella and flagellar structure maintainance. The QRICH2 gene has been associated with the disease, Spermatogenic failure. Synonyms for this target antigen include glutamine-rich protein 2. QRICH2 gene orthologs have been reported in the mouse, bovine, frog, chimpanzee and chicken species. Some QRICH2 antibodies may have been used in research and have associated citations. Immunocytochemistry is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
