Anti-CSTF2 antibodies are used in the immunodetection of the protein cleavage stimulation factor subunit 2. In humans, the canonical protein has a reported length of 577 amino acid residues and a mass of 61 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. CSTF2 is reported to be one of the multiple factors required for polyadenylation and 3'-end cleavage of mammalian pre-mRNAs. Synonyms for this target antigen include CF-1 64 kDa subunit, CSTF 64 kDa subunit, cleavage stimulation factor 64 kDa subunit, cleavage stimulation factor, 3' pre-RNA, subunit 2, 64kD, and CstF-64. CSTF2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CSTF2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
