Thirty-five variant lectins were prepared by mutations of two amino acids within the carbohydrate-recognition domain of Maackia amurensis hemagglutinin (MAH). Each lectin showed unique carbohydrate specificity according to their bindings to soluble polyacrylamide with various mono- and oligosaccharides and to glycophorin A. The relative intensity of the bindings of carcinoma, myeloid, fibroblastic, and melanoma cells to immobilized MAH variant lectins was examined. Each cell line showed distinct profiles regarding the number of cells bound to wild-type and 35 MAH variants and the differences and the similarities in these binding profiles were quantitatively documented by the cluster analysis. The cell lines were classified into several groups and these groups surprisingly corresponded to the lineage of the cells. These results indicated that a library of mutated MAH is useful as a tool for the profiling of various cells based on the variations of the surface glycans.

UI MeSH Term Description Entries
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D011485 Protein Binding The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments. Plasma Protein Binding Capacity,Binding, Protein
