Anti-9F antibodies enable researchers to detect and measure the 9F antigen in biological samples. This target is a reported synonym of the FAM50A gene, which encodes family with sequence similarity 50 member A. This protein is known to function in chromatin organization and mRNA processing, among other biological roles. The human version of 9F has a canonical amino acid length of 339 residues and a protein mass of 40.2 kilodaltons. 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 DXS9928E and HXC-26.
