Abstract

Lectins are carbohydrate-binding proteins that can modulate cellular activity through cell membrane glycoproteins. A cell-based binding was set up to screen the lectin-like substances in natural products. Lectins, after binding to tumor cells, are detected with a biotinylated carbohydrate-polyacrylamide complex by ELISA. Sugar specificity can also be determined within the assay.
