title: An attempt to separate mononuclear cells fused with human red blood cell-ghosts from a cell mixture treated with HVJ (Sendai virus) using a fluorescence activated cell sorter (FACS II).
abstract: Nucleated cells (Ehrlich ascites tumor cells or L strain cells) and human red blood cells (RBC)-ghosts were mixed and fused by ultraviolet-inactivated HVJ (Sendai virus). The cell mixture was stained with FITC conjugated anti-RBC ghost antiserum and then applied to FACS II apparatus. The apparatus sorted mononuclear cells fused with RBC-ghosts from the cell mixture on the basis of both the light scattering and fluorescence profiles. When the same procedure was carried out on a mixture containing cells and intact human RBC, the cells sorted by this method were cells into which hemoglobin had been injected. The sorted cells were capable of forming colonies in culture. This sorting method may be useful for collecting cells in which macromolecules have been injected artificially by fusion of RBC-ghosts enclosing macromolecules.
