Psophocarpus tetragonolobus Lectin (PTL/PTA I) - Pure
Price: Regular price $107.88
Product Description
Psophocarpus tetragonolobus lectin (PTL I, psophocarpin B1, a storage protein with chymotrypsin inhibitory activity), is isolated from winged bean seeds and purified by affinity chromatography. The seed contains two lectins in which PTL I is the basic of the two. PTL I is a dimeric glycoprotein with specificity to GalNAc, with eluting sugar GalNAc. This lectin agglutinates trypsinized rabbit and human erythrocytes (type A and B) but not trypsinized human type O erythrocytes. PTL I recognizes blood group A-substance derived oligosaccharides such as trisaccharide GalNAc?1-3Gal?1-4Glc.
