Further functional studies

Abstract

The assessment of cell surface antigen expression on cells is probably the most common use of flow cytometry. However, cells may be interrogated in many other ways by flow cytometry to measure functional properties. The change in expression of receptors with time may be assessed or the interaction of one cell type with another may be measured. In addition, changes in enzyme activity and membrane potential may be assayed. Experiments to show phagocytosis and release of bioactive molecules may also be performed.
