iFluor® 594-Wheat Germ Agglutinin (WGA) Conjugate
Wheat germ agglutinin (WGA) is a lectin that binds to N-acetyl-D-glucosamine and sialic acid. It is of the most studied and useful lectins for it biological applications. Since WGA binds to glycoconjugates its derivatives and conjugates are widely used to label cell membranes and fibrotic scar tissue for fluorescence imaging and analysis. The carbohydrate-binding specificity of WGA is directed against sequences of β-1,4-GlcNAc-linked residues, the chitodextrins. Each monomer contains two identical, non-interacting binding sites which are complementary to 3 or 4 β-1,4-GlcNAc units. Of the monosaccharides examined, only GlcNAc binds to WGA. ManNAc does not bind and GalNAc binds only weakly. iFluor®594 conjugate of WGA might be the brightest red fluorescent WGA conjugate. It exhibits the bright, red fluorescence of the iFluor® 594 dye. iFluor®594 WGA conjugate binds to sialic acid and N-acetylglucosaminyl residues as AF594 WGA conjugate does.
Live HeLa cells were stained with iFluor® 594-Wheat Germ Agglutinin (WGA) Conjugate at 5 µg/mL for 30 minutes followed by Hoechst 33342 (AAT Cat# 17535). Image was acquired using fluorescence microscopy using Cy3/TRITC and DAPI filter set.
