Anti-NFI antibodies enable researchers to detect and measure the NFI antigen in biological samples. This target is a reported synonym of the NFIC gene, which encodes nuclear factor I C. This protein is known to function in DNA replication and the regulation of transcription, among other biological roles. The human version of NFI has a canonical amino acid length of 508 residues and a protein mass of 55.7 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include CTF, CTF5, and NF-I. Western Blot is a widely used application for the NFI antibodies listed below. In addition, ELISA is also a common application.
