Product Description

Allium sativum lectin (ASA) is isolated from garlic bulbs and purified by affinity chromatography, followed by gel filtration. It is a dimer of two subunits with a molecular weight of 24,000 with an isoelectric point that ranges between pH 7.2 and pH 7.4.

This lectin`s sugar specificities can be elucidated by hemagglutination inhibition and a coupled enzyme-based assay. The hemagglutination inhibition study helps confirm this lectins specificity for D-mannose, while a sensitive enzyme-based assay can examine detailed binding specificities. Binding sites of ASA accommodate a number of ?1-2-linked mannose residues, with an eluting sugar of mannose. Interaction with glycoproteins not only suggests that the lectin recognizes internal mannose but that also binds to the core pentasaccharide of N-linked glycans even when it is sialylated. Although the binding site can withstand terminal sialic acids and the penultimate galactose residues, the removal of sialic acids enhances potency.
