Biotium Live Bacterial Gram Stain Kit - 800 assays
Supplier: Biotium 32000
The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF594 to stain the surface of gram-positive cells with red fluorescence. The kit also includes DAPI to stain all bacteria. Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. CF594 is spectrally similar to Texas Red, but with brighter fluorescence. The kit also includes DAPI to stain the DNA of all bacteria with blue fluorescence. Gram-positive bacteria stained using this kit will show a fluorescent blue interior and fluorescent red cell surface, while gram-negative bacteria will be stained with blue fluorescence only. This kit contains sufficient reagent for 800 assays.
