Electrokinetic alteration of the surface of herpes simplex virus infected cells.
Changes induced in the ionic composition of the surface of herpes simplex virus (HSV) infected cells were evaluated by whole cell electrophoresis and isoelectric focusing. The kinetics of the progressive decline in cell electrophoretic mobility (a measurement of negative surface charge density) after infection corresponded to the production of infection virus. The observed HSV-induced increase in cell isoelectric focusing pH demonstrated that the electrokinetic cell surface became ionically more positive. The nature of the ionic changes were investigated using a series of specific reagents in conjunction with cell electrophoresis. Infected cells had 2.4 times surface binding sites for the amino-specific reagent 4-acetamide-4'-isothiocyanostilbene-2,2'-disulphonic acid. A relationship between these virus-induced amino groups and HSV surface antigens was indicated by the similar kinetics of their appearance and electrophoretic neutralization by HSV antibodies.

Cell electrophoresis research directed toward clinical cytodiagnosis.
The application of cell electrophoresis to cytodiagnosis requires that a scientifically established basis exists for identifying abnormal cells electrophoretically, that research to detect such differences in the cytodiagnostic setting is possible and that a rapid and simple method of cell electrophoresis is adaptable to the clinical setting. Data are presented indicating modifications of electrophoretic mobility due to herpes simplex virus type 1 infection and Rous sarcoma virus transformation of culture cells. A simple apparatus for electrophoretically separating cells on a density gradient and collecting them for subsequent analysis is described, and results of experiments with this apparatus are consistent with those obtained by microscopic electrophoresis. Laser-doppler spectroscopic electrophoresis is suggested as a rapid method adaptable to clinical application.
