An array of stains and assays for microbiological organisms such as bacteria, yeast and viruses.
For bacteria, we offer viability assays, fluorescent gram stain kits, and nucleic acid stains.
For yeast, find viability assays and other stains.
Learn more about viability PCR using PMAxx™ or PMA, a fast, quantitative method to measure viability of the organisms in your sample.
A convenient assay for distinguishing between gram-negative and gram-positive, as well as live versus dead 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 all bacteria.
LysoView™ dyes label lysosomes in live cells, and are available with blue, green, visible red, and far-red fluorescence. Far-red LysoView™ 650 is compatible with super-resolution imaging by STED and SIM. Note: LysoView™650 (70059 and 70059-T) is temporarily unavailable.
PMA (propidium monoazide) is a high affinity photoreactive DNA binding dye invented by scientists at Biotium for viability PCR of bacteria and other microorganisms.
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.
PMA Enhancer for Gram Negative Bacteria was designed to improve PMA- and PMAxx™-mediated discrimination between live and dead gram-negative bacteria.
