The acceptor sugar of WGA is N-acetylglucosamine, which preferentially binds to dimers and trimers of this sugar. WGA can bind oligosaccharides with n-acetylglucosamine or chitosan at the end, a structure common to many serum and membrane glycoproteins. Bacterial cell wall peptidoglycans, chitin, chondrosaminoglycans and glycolipids can also bind WGA.
