Purification and cDNA cloning of a lectin and a lectin-like protein from Apios americana Medikus tubers.

An Apios americana lectin (AAL) and a lectin-like protein (AALP) were purified from tubers by chromatography on Butyl-Cellulofine, ovomucoid-Cellulofine, and DEAE-Cellulofine columns. AAL showed strong hemagglutinating activity toward chicken and goose erythrocytes, but AALP showed no such activity toward any of the erythrocytes tested. The hemagglutinating… CONTINUE READING
