Invitrogen™ ReadyProbes™ Cell Viability Imaging Kit, Blue/Green DFS Item

Determine the viability of cells quickly and easily. Invitrogen™ ReadyProbes™ Cell Viability Imaging Kit, Blue/Green is a ready-to-use assay kit for use in for fluorescence microscopy, fluorescence microplate readers, and flow cytometry.

Manufacturer:  Invitrogen™ LSR37609

Catalog No. R37609

Includes: 3 x 2.5mL NucBlue Live, 3 x 2.5mL NucGreen Dead



ReadyProbes™ Cell Viability Imaging Kit, Blue/Green contains NucBlue™ Live reagent (Hoechst 33342) and NucGreen™ Dead reagent. Just add 2 drops of each stable reagent (at room temperature) to 1mL of cell growth media, then determine viability by counting total vs dead cells. NucBlue™ Live reagent stains the nuclei of all the cells and can be detected with a standard DAPI filter. NucGreen™ Dead reagent stains only the nuclei of cells with compromised plasma membrane integrity and is detected using a standard FITC/GFP (green) filter set.

  • NucBlue™ Live reagent: stains the nuclei of all cells; detected with a standard DAPI filter (excitation/emission maxima: 360/460nm)
  • NucGreen™ Dead reagent: stains only the nuclei of dead cells with compromised plasma membranes; detected with standard FITC/GFP (green) filter set (excitation/emission maxima: 504/523nm)

Suggestions for use

  • NucBlue™ Live and NucGreen™ Dead reagents may be added directly to cells in full growth media or a compatible buffer solution.
  • In most cases, 2 drops/mL and an incubation time of 5 to 30 minutes will give bright nuclear staining; however, optimization may be needed for some cell types, conditions, and applications. In such cases, simply add more or fewer drops until the optimal staining intensity is obtained.


Store at 2° to 8°C, or at room temperature.
