Anti-host cell factor C2 antibodies are used for the immunodetection of the protein encoded by the HCFC2 gene. In humans, the canonical protein has a reported length of 792 amino acid residues and a mass of 86.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be highly expressed in the testis. It is noted to be involved in chromatin remodeling and the regulation of transcription. Other names for this target antigen include HCF2, host cell factor 2, C2 factor, and HCF-2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some host cell factor C2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
