Wheat Germ Agglutinin (WGA), CF®488A conjugated

Wheat germ agglutinin (WGA) is a carbohydrate-binding lectin that has high affinity for sialic acid and N-acetylglucosamine moieties of glycoproteins. As a result, WGA conjugates will label yeast bud scars and the cell membrane of gram bacteria and mammalian cells.

• Stain yeast bud scars as well as the cell membrane of gram bacteria and mammalian cells or tissues
• Suitable for Western Blot, ELISA, immunohistochemistry and other standard immunoassay applications
• A retrograde or anterograde neuronal tracer
• Withstands fixation and permeabilization
• Choice of 13 CF® dyes from UV to near-infrared or HRP
• Superior CF® dyes are bright, photostable, and water-soluble

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 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.
