Light-microscopical demonstration of different cell membrane structures of human peripheral blood lymphocytes (PBI).

Labelling of membrane structures in human peripheral blood lymphocytes is achieved by a Fe-(III)-hydroxide-glycane-complex. According to the distribution of labelled structures, coarse-granular clustered (about 80%) and fine-granular diffuse marked peripheral blood lymphocytes can be distinguished. Each of these populations seems to have morphologically discernible subpopulations.
