Cells can reveal a lot about the performance of new drug compounds. Being confined to a finite number of time points or cellular states per assay limits what precious information we can get from these cells.

Fortunately, there is now a way to get more from cell assays. ChromaLive is an indefinitely non-toxic and mix-and-read fluorescent stain that generates a unique signature for every cellular state.

ChromaLive Features


Read in different fluorescent channels with ChromaLive

Exc/Em: 488/600nm, 488/700 nm, 561/600 nm


Monitor whole-cell changes rather than specific biomarkers

ChromaLive teases apart phenotypes by highlighting cell morphology and by monitoring spectral variation in the 488nm excitation channel


Use ChromaLive in a variety of cell models

Fix your cells with ChromaLive Fix and use in any cell such as stem cells or primary cells

“ChromaLive is surprisingly easy-to-use. It Images yield a very good signal-to-noise ratio. I was able to quickly differentiate apoptotic cells from viable ones in a high-content image analysis. Plus, customer support was outstanding!”

 “[There] are six kinds of patient CLL cells that we identified using those dyes, and we have found a drug combination, now in clinical trials, that effectively kills cells for one patient cohort”

“My cells are unaffected. I can easily tell between live and dead cell states, and even tell, apart the different immune cells in my model.”
