Anti-RSF1 antibodies are used in the immunodetection of the protein remodeling and spacing factor 1. In humans, the canonical protein has a reported length of 1441 amino acid residues and a mass of 163.8 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. RSF1 is a regulatory subunit of the ATP-dependent RSF-1 and RSF-5 ISWI chromatin-remodeling complexes, which form ordered nucleosome arrays on chromatin and facilitate access to DNA during DNA-templated processes such as DNA replication, transcription, and repair. Synonyms for this target antigen include XAP8, p325, HBV pX-associated protein 8, hepatitis B virus x-associated protein, p325 subunit of RSF chromatin-remodeling complex, and HBXAP. RSF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RSF1 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.
