Abstract: The cell surface is the interface between the cell and its environment. The surface acts to regulate cell function through antigens, receptors, cell-cell interaction, and other factors. One important and measurable property of the cell surface is charge. Surface charge results from the accumulation of exposed charge groups at the external surface of the cell membrane, and is peripheral to the region of transmembrane ion separation which defines transmembrane potential. The surface of normal human cells is negatively charged due to the presence of acidic oligosaccharide groups at the terminal regions of membrane glycoproteins (1).
