Thermo Fisher Scientific offers a broad selection of fluorescent wheat germ agglutinin conjugates. These lectins can bind to carbohydrates and are available conjugated to Alexa Fluor™, Alexa Fluor™ Plus, and other fluorescent dyes. Fluorescent wheat germ agglutinin conjugates are valuable tools in molecular and cell biology research, enabling researchers to label the plasma membrane in fluorescence imaging and cell painting assays, and study and analyze glycosylation patterns and glycan-mediated processes in cells and tissues.

Thermo Fisher Scientific offers bright conjugates of wheat germ agglutinin (WGA) with Alexa Fluor, Alexa Fluor Plus, and other dyes. WGA is a cell impermeant stain that selectively binds to N‐acetylglucosamine and N‐acetylneuraminic acid (sialic acid) residues, which are often found on cell membranes. Fluorescent WGA conjugates provide selective labeling of the plasma membrane with minimal background in many cell types that is retained after formaldehyde fixation and permeabilization with Triton X-100.

These fluorescent lectin conjugates can also be used to label fixed cells; however, to avoid labeling intracellular components, formaldehyde-fixed cells should not be permeabilized before labeling. Fluorescent WGA conjugates are used as plasma membrane stains along with other cellular markers in cell painting assays to provide a phenotypic readout of cell health or cytotoxicity. The Wheat Germ Agglutinin, Alexa Fluor 555 Conjugate is included in the Image-iT Cell Painting Kit (Cat. Nos. I65000 and I65500).

WGA conjugates are also used as retrograde tracers for neuronal tracing experiments and have been shown to cross synapses. These fluorescent lectins are applicable in microbiology studies to label yeast bud scars, the cell membrane of gram-positive but not gram-negative bacteria, and chitin in fungal cell walls. In solution, WGA exists as a heterodimer with a molecular weight of approximately 38,000 Daltons and is normally cationic under physiological conditions. Our WGA conjugates have been used in variety of applications, including immunofluorescence (IF), immunohistochemistry (IHC), flow cytometry (FC), and a wide range of chemical, biochemical and immunological assays.

Thermo Fisher Scientific offers a broad selection of fluorescent wheat germ agglutinin conjugates with options covering the entire wavelength range. The Wheat Germ Agglutinin Sampler Kit (Cat. No. W7024) includes introductory samples of four fluorescent WGAs: Alexa Fluor 350, Oregon Green 488, tetramethylrhodamine, and Texas Red-X conjugates. The red-fluorescent Alexa Fluor 594 wheat germ agglutinin (WGA) conjugate is also included in the Image-iT LIVE Plasma Membrane and Nuclear Labeling Kit (Cat. No. I34406). The Texas Red-X WGA conjugate can be purchased in the ViaGram Red+ Bacterial Gram Stain and Viability Kit (Cat. No. V7023) to differentiate gram-positive and gram-negative bacteria.
