LIVE/DEAD® Cell Viability Assays



 Invitrogen offers complete solutions for easy, sensitive determination of cell viability, cell vitality and compound cytotoxicity.  These fluorescence-based LIVE/DEAD® assays can be used to examine animal cells, bacteria, yeast and fungi. Specific LIVE/DEAD® assays can be used for flow cytometry, microscopy, or microplate formats. Fluorescent dyes used in the viability assays range from blue to near-IR emission.  Our LIVE/DEAD® fixable viability assays permit fixation which enables intracellular staining and neutralization of pathogens.
 
LIVE/DEAD® Kits for Mammalian Cells


These kits combine fluorescent reagents to yield, in most cases, two-color discrimination of the population of live cells from the dead-cell population without any wash steps. These are ideal for high-throughput screening, imaging, fluorometry and flow cytometry.

LIVE/DEAD® Kits for Yeast and Fungi


Our LIVE/DEAD® Yeast Viability Kits provide an extremely simple and sensitive assay for discriminating viable yeast and fungi in complex mixtures or in pure cultures. The Yeast Viability Kit uses FUN 1 dye and Calcofluor White M2R. The FungaLight™ Yeast Viability Kit uses 2 nucleic acids stains.

LIVE/DEAD® Fixable Stains for Flow Cytometry


LIVE/DEAD® Fixable Dead Cell Stain Kits allow you to accurately distinguish live and dead cells when performing intracellular staining in flow cytometry. Additionally, the dyes in the kits react covalently with protein so that the discrimination is completely preserved following fixation of the sample by formaldehyde, under conditions that inactivate pathogens.
LIVE/DEAD® Kits for Bacteria


The LIVE/DEAD® BacLight™ Bacterial Viability Kits provide two different nucleic acid stains to rapidly distinguish live bacteria with intact plasma membranes from dead bacteria with compromised membranes.
