Maackia amurensis Lectin (MAA/MAL II) is a plant lectin known for its specific carbohydrate recognition capabilities. It binds to molecules with particular sugar structures, exhibiting a high affinity for α-2,3-linked sialic acid, making it a precise probe for biomolecular binding. Maackia amurensis Lectin (MAA/MAL II) is utilized in the discovery of disease-related biomarkers and the investigation of cancer pathologies.
