Anti-RFC2 antibodies are used in the immunodetection of the protein replication factor C subunit 2. In humans, the canonical protein has a reported length of 354 amino acid residues and a mass of 39.2 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Activator 1 small subunits protein family, RFC2 is known to be involved with DNA repair and DNA replication. Synonyms for this target antigen include A1 40 kDa subunit, RF-C 40 kDa subunit, activator 1 subunit 2, replication factor C (activator 1) 2, 40kDa, and RFC40. RFC2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RFC2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry and Immunohistochemistry are also common applications.
