Maackia Amurensis Lectin I (MAL I), Unconjugated, 5 mg, is the leucoagglutinin or mitogenic isolectin from Maackia seeds. Maackia amurensis lectin I binds gal (beta-1,4) glcNAc but tolerates substitution of N-acetyllactosamine with sialic acid at the 3 position of galactose. However, MAL I does not appear to bind this structure when substitution with sialic acid is on the 6 position of galactose.
