摘要：The binding of fluorescein-conjugated Concanavalin A to the cell surface has been studied in normal and transformed cells in interphase and mitosis. Binding to the cell surface was in the form of an incomplete ring of fluorescence, and the binding was inhibited by [α]-methyl-D-mannopyranoside. All the cells were fluorescent when treated with 25-250 {micro}g/ml of fluorescent Concanavalin A. With 10 {micro}g, the cells were all fluorescent after 30 min of binding, but after 0.5-5 min with 10 {micro}g or 30 min with 1 or 2.5 {micro}g, transformed interphase cells showed a higher percentage of cells with surface fluorescence than did normal interphase cells. Trypsinized normal and transformed interphase cells showed the same fluorescence. Binding with 2.5 {micro}g at 4{degrees} instead of at 24{degrees
