Biomedical and clinical applications of automated single cell electrophoresis.
The automated single cell electrophoresis microscope Parmoquant has been used for the discrimination of lymphocytes and the study of the interaction of substances with cells and synthetic particles. Electrophoretic histograms allowed the determination of changes in the proportion of lymphocyte populations after kidney transplantation, during dialysis treatment, open heart surgery and during pregnancy. Discrimination of leukemic cells on the basis of electrophoresis was used as an additional parameter in diagnosis. In a mouse tumor model, histogram determination enabled the in vivo effect of the tumor necrosis factor on immune cells to be evaluated. Cell electrophoresis was shown to be suitable to detect the influence of antibodies, lectins and bacteria on the cell surface. Protein adsorption was studied on synthetic particles using cell electrophoresis. This method was applied to investigate the phenomena of blood interaction with biomaterials used in artificial organs and to determine differences in the protein composition of serum or other body fluids connected with diseases.
