Elucidation of lectin receptors by quantitative inhibition of lectin binding to human erythrocytes and lymphocytes. 1976

T Kawaguchi, and T Osawa

The binding to normal and sialidase-treated human erythrocytes and lymphocytes of four 125I-labeled lectins [Maackia amurensis hemagglutinins (MAM and MAH), Ricinus communis hemagglutinin (RCH), and Bauhinia purpurea hemagglutinin (BPH)] was studied in detail. The quantitative inhibition assays against the lectin binding to the cells were also performed with various glyco-proteins and glycopeptides as inhibitors. The comparison of the inhibition constants of the inhibitors thus obtained with the association constants of the lectins to the cells permitted estimation of the relative receptor activities of cell surface glyco-proteins toward the lectins.

UI	MeSH Term	Description	Entries
D007467	Iodoproteins		Iodopeptides
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
