CytoTrack Cell Proliferation Assays

Resolve up to Ten Cell Divisions

CytoTrack Cell Proliferation Assays efficiently stain live cells to obtain excellent resolution of each cell division generation. CytoTrack Dyes allow you to measure cell proliferation in live cells. As the labeled cells divide, the concentration of the dye is halved and the proliferation can be measured based upon the reduced levels of fluorescence in subsequent generations. These dyes are available in a range of excitation and emission spectra for convenient incorporation into multicolor flow cytometry panels.

For convenient CFSE staining, we also offer a cell proliferation assay featuring CFDA-SE dye to monitor proliferation.

CytoTrack Cell Proliferation Dyes Key Benefits

The benefits of using CytoTrack Cell Proliferation Dyes are numerous and these include:

• Detect intracellular targets - as they are compatible with standard formaldehyde-containing fixatives and saponin-based permeabilization buffers
• Suitable for multicolor cell analysis: range of excitations and emissions for compatibility with fluorescent proteins or fluorophore-labeled antibodies
• No washing required, use the cell proliferation assay directly with your cell culture media
• Resolve up to 10 cell divisions compared to CFSE

Proliferation Dyes

We also have reagents and kits to detect and measure proliferation, suitable for use in ELISA, microscopy, and flow cytometry as well as antibodies to detect common cell proliferation markers and BrdU incorporation into newly synthesized DNA.
