Anti-MCRS1 antibodies are used in the immunodetection of the protein microspherule protein 1. In humans, the canonical protein has a reported length of 462 amino acid residues and a mass of 51.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably expressed in the testis, and at lower levels in spleen, thymus, prostate, uterus, small intestine, colon and leukocytes. MCRS1 is known to be involved with chromatin remodeling and DNA repair. Synonyms for this target antigen include INO80Q, MCRS2, MSP58, P78, 58 kDa microspherule protein, and ICP22BP. MCRS1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of MCRS1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
