Vector Laboratories Wheat Germ Agglutinin (WGA) Rhodamine-labeled 5 mg
Supplier: Vector Laboratories RL10225
Wheat germ agglutinin (WGA) contains a group of closely related isolectins with a pI of about 9 that bind N-acetylglucosamine (preferentially the dimers and trimers of this sugar) and oligosaccharides containing terminal N-acetylglucosamine or chitobiose, structures common to many serum and membrane glycoproteins. Bacterial cell wall peptidoglycans, chitin, cartilage glycosaminoglycans, and glycolipids can also bind WGA, and this lectin is used for the purification of insulin receptors and for neuronal tracing. Native WGA also interacts with some glycoproteins via sialic acid residues (see succinylated WGA). This rhodamine-labeled WGA features a ratio of fluorophores to lectin protein that provides optimal staining (excitation 575 nm, emission 600 nm). It is supplied as a solution essentially free of unconjugated fluorophores.
