Vector Laboratories Griffonia (Bandeiraea) Simplicifolia Lectin I (GSL I, BSL I), Fluorescein-labeled 5 mg

Supplier:  Vector Laboratories FL11015

Griffonia simplicifolia lectin I (GSL I) is a family of glycoproteins w/ molecular weights of approximately 114 kDa. 2 subunits ("A" & "B") have slightly different molecular weights & combine to form tetrameric structures, resulting in five isolectins. The "A"-rich lectin preferentially agglutinates blood group A erythrocytes & appears to be specific for α-N-acetylgalactosamine residues, while the "B"-rich lectin preferentially agglutinates blood group B cells & is specific for α-galactose residues. Our GSL I is a mixture of the five isolectins & binds several glycoproteins, including laminin. This fluorescein-labeled GSL I features a ratio of fluorophores to lectin protein that provides optimal staining (excitation 495 nm, emission 515 nm). Supplied as a solution essentially free of unconjugated fluorophores, it is preserved with sodium azide. The recommended inhibiting/eluting sugar is a mixture of 200 mM galactose & 200 mM N-acetylgalactosamine.
