Cellular location of 'liver-specific' antigen F

Three mouse monoclonal antibodies against Type 1 murine 'liver-specific' antigen F and one rat monoclonal antibody against human antigen F were produced. These monoclonals recognize antigenic determinants common to Type 1 and Type 2 mouse and human antigen F. By immunolabelling with beta-galactosidase, antigen F could be demonstrated in the cytoplasm of hepatocytes, tubules of the kidney, and perikarya of neurons of the central nervous system. F antigens isolated from liver, kidney, and brain all have molecular weights of around 40,000.
