Fluorescent Gram Stains
Wheat Germ Agglutinin (WGA) binds specifically to the cell wall of gram-positive bacteria. Therefore, when conjugated to a fluorescent dye, it can be used as a quick, sensitive, fluorescent gram stain, that can be used in conjunction with other fluorescent stains. Biotium offers WGA conjugated to a wide variety of bright, stable CF® Dyes.
