title: Immunofluorescence detection of liver cell membrane autoantibodies using PLC/PRF/5 cells.
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.
