Anti-HF.18 antibodies enable researchers to detect and measure the HF.18 antigen in biological samples. This target is a reported synonym of the ZNF8 gene, which encodes zinc finger protein 8. This protein is known to function in the regulation of transcription, among other biological roles. The human version of HF.18 has a canonical amino acid length of 575 residues and a protein mass of 65 kilodaltons. It is reported to be localized in the nucleus of cells. This target antigen may also be known as Zfp128.
