[The carbohydrate-binding molecules of the surface membranes of immune system cells]

Data are presented on the use of biotinylated polyacrylamide attached carbohydrates as immunohistochemical probes. Their high specificity is shown, the optimal conditions of performing the immunocytochemical reaction are described. Using a panel of probes, oligosaccharide-binding molecules were revealed on the surface of lymphocytes from peripheral blood, lymph nodes and pleural effusions, and in the cytoplasm of phagocytic cells. Data on the expression of endogenous lectin-like molecules in different cells are presented.
