Product Description

This product is wheat germ agglutinin (WGA) labeled with Biotium’s CF® Dyes or HRP. WGA is a carbohydrate-binding lectin that has high affinity for sialic acid and N-acetylglucosamine. CF® Dye WGA conjugates can be used to stain glycoproteins that have these sugar moieties. WGA is commonly used to label glycoproteins for imaging of the plasma membrane in live or fixed cells, for staining of tissue sections, or for western blotting. WGA also is useful as a retrograde or anterograde neuronal tracer. Staining with WGA conjugates may be tissue- and cell-type dependent.

WGA can be used as a gram stain to fluorescently label gram+ bacteria but not gram- bacteria. WGA also binds to the bud scars on budding yeast such as Saccharomyces cerevisiae. See our Cellular Stains Table for more information on how our dyes stain various organisms.

WGA HRP conjugate can be used for Western Blot, ELISA, immunohistochemistry and other standard immunoassay applications.
