title: Hepatitis B virus and host cell membrane antigens on a primary hepatocellular carcinoma cell line.
abstract: We have defined some membrane antigens of the cultured hepatocellular carcinoma cell line PLC/PRF/5, which contains the integrated genome of hepatitis B virus. Using fluoresceinated antibodies, we identified HLA Class 1 glycoprotein and HB surface antigen on the membrane. Only in a minority of cells was physical association of these antigens demonstrated by co-capping. The presence of a "division" antigen was indicated by reactivity of the cells with the murine monoclonal antibody OKT9.
