Maackia amurensis lectin (MAA/MAL I) is a leukocyte lectin isolated from amurensis seeds and purified by affinity chromatography. MAA I can be used to detect N-chain glycans containing the trisugar Siaα2-3Galß1-4GlcNAc. This lectin does not make people with one blood type more prone to agglutination than those with another, and agglutination can be inhibited by salivary lactose or higher concentrations of lactose. Although MAA I and MAA II are similar in size and structure, this lectin is a more potent mitogen and exhibits a lower blood clotting capacity than MAA II.
