[Laser spatial scanning in flow cytometry]

The main flow laser cytometry principles, based on the elastic light scattering, spheres of its applications, problems of its realization and utilization in the immunological investigations and diagnostics are analysed. The experimental model of a flow cytometer with laser probing beam space scanning, originally proposed by the authors, is described. The apparatus was tested by polystyrene latex spheres and biological objects. The experiments showed that the achieved sensitivity was enough to register red blood cells, their complexes and bacterial cells.
