Live-or-Dye™ Fixable Viability Staining Kits
Live-or-Dye™ Fixable Viability Staining Kits are designed for discrimination between live and dead cells during flow cytometry. Live/dead stains are useful probes to include when analyzing cell surface protein expression by flow cytometry, because they allow intracellular fluorescence signal from dead cells with permeable plasma membranes to be excluded from analysis.
Bacterial Viability and Gram Stain Kit
The Bacterial Viability and Gram Stain Kit contains three components: CF®488A-WGA, DAPI, and EthD-III solutions 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.
PMA Real-Time PCR Bacterial Viability Kit – E. coli O157:H7 (Z3276)
This kit contains primers for amplification of E. coli strain O157:H7 Z3276 gene, with reagents sufficient to treat 80 bacterial cultures with PMA or PMAxx™, and perform 200 PCR reactions.
PMA Dye, 20 mM in H2O
PMA (propidium monoazide) dye is a DNA modifier invented by scientists at Biotium. It is a photo-reactive DNA-binding dye that is useful for determination of microbial viability by qPCR.
