Abstract
Detection of liver cell membrane autoantibodies is routinely performed by immunofluorescence testing of patient sera on rabbit hepatocyte suspensions. We have investigated the possible use of cells from the PLC/PRF/5 human hepatoma cell-line. These cells were employed as substrate in an immunofluorescence test which was compared with the conventional rabbit hepatocyte assay. We found a close correlation between the results obtained with these different substrates on visual reading. We furthermore compared visual reading of immunofluorescence preparations with flow-cytometrical analysis of immunostained cell suspensions. The results with these different methods were largely confirmatory. The PLC/PRF/5 cells are easily available and should therefore be regarded as a highly valuable new substrate for detection of liver cell membrane autoantibodies. Flow cytometry appears to be a technically simple and reliable method for quantitative analysis.
