Vector Laboratories Griffonia (Bandeiraea) simplicifolia lectin I (GSL I, BSL I) Biotinylated 2 mg

Supplier:  Vector Laboratories B11052

Griffonia simplicifolia lectin I (GSL I) is a family of glycoproteins with molecular weights of approximately 114 kDa. Two subunits ("A" and "B") have slightly different molecular weights and combine to form tetrameric structures, resulting in five isolectins. The "A"-rich lectin preferentially agglutinates blood group A erythrocytes and appears to be specific for α-N-acetylgalactosamine residues, while the "B"-rich lectin preferentially agglutinates blood group B cells and is specific for α-galactose residues. Our GSL I is a mixture of the five isolectins that binds several glycoproteins, including laminin. This conjugate features a ratio of biotin to lectin protein that provides optimal avidin/streptavidin and lectin binding activity. Supplied essentially free of unconjugated biotins, it is preserved with sodium azide.
