Invitrogen™ Lectin SBA From Glycine max (soybean), Alexa Fluor™ 647 Conjugate

Lectins are oligomeric proteins with saccharide-binding sites that can recognize and bind particular glycoconjugates. The lectin soybean agglutinin (SBA), which is isolated from Glycine max, selectively binds terminal α- and β-N-acetylgalactosamine and galactopyrano- syl residues. This lectin exists as a tetramer and has a molecular weight of approximately 120,000 daltons.1 Fluorescent lectins are versatile probes with diverse applications, including detection of cell surface and intracellular glycoconjugates by microscopy and flow cytometry, localization of glycoproteins in gels, precipitation of glycoproteins in solution and agglutination of specific cell types.1 Molecular Probes® fluorescent SBA conjugates are prepared with three of our very best fluorophores.
