This tetrameric lectin consists of 44,000 dalton subunits and does not require divalent cations for binding. Binding appears to be highest for glycoconjugates containing galactosyl (b-1,3) N-acetylgalactosamine structures but oligosaccharides with a terminal alpha linked N-acetylgalactosamine can also bind. Although binding specificity is similar to that of peanut agglutinin, tissue staining patterns of these two lectins are distinct.
