Unconjugated Griffonia (Bandeiraea) Simplicifolia Lectin II (GSL II, BSL II)

This lectin is a dimeric glycoprotein composed of two subunits of nearly identical size with each subunit having disulfide-linked chains and a binding site for α- or β-linked N-acetylglucosamine residues. Unlike other N-acetylglucosamine specific lectins, increasing the number of N-acetylglucosamine residues beyond two does not improve affinity. GSL II has been reported to be unique in its ability to recognize exclusively α- or β-linked N-acetylglucosamine residues on the nonreducing terminal of oligosaccharides.

Inhibiting/Eluting Sugar: Chitin Hydrolysate or 200 mM N-acetylglucosamine
