A rapid, objective method for the detection of lymphocytotoxic antibodies using flow cytometry.
Whilst several centres have reported lymphocytotoxic antibody detection using single and dual fluorescent stains with analysis of the fluorescence emitted from the cell population present in a well of a multiwell plate, problems are encountered with cell concentration and light emission overlap. A method we have developed using flow cytometry produces similar values of percentage cell death using single or double staining techniques (correlation coefficient = 0.9896). This method is not influenced by slight variation in cell number or light emission overlap. The effect of introducing red cell impurities into the normal lymphocyte preparation is described.
