Bacterial Viability and Gram Stain Kit
A convenient assay for distinguishing between gram-negative and gram-positive, as well as live versus dead bacteria.
Live Bacterial Gram Stain Kit
Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF®594 to stain the surface of gram-positive cells with red fluorescence. The kit also includes DAPI to stain the DNA of all bacteria with blue fluorescence.
Yeast Viability Staining Kit
The Yeast Viability Staining Kit is a fluorescent assay to determine yeast viability. Each kit contains two fluorescent components, CF® Dye-labeled Concanavalin A (ConA) and Live-or-Dye® viability dye.
Concanavalin A (Con A) CF® Dye Conjugates
This product is concanavalin A (Con A) labeled with our superior fluorescent CF® dyes. Con A is a widely used lectin that selectively binds to a-mannopyranosyl and a-glucopyranosy residues, found in the cell wall of yeast and fungi, and the cell membrane of mammalian cells.
CF® Dye PNA Lectin (Arachis hypogaea)
This product is Arachis hypogaea (peanut) PNA lectin labeled with our superior CF® dyes. Lectin PNA is specific for terminal β-galactose and binds preferentially to a commonly occurring structure, galactosyl (β-1,3) N-acetylgalactosamine.
