Great experience using it! I can't go back to using the MTT method ever again!
Cell viability
Compared to the traditional MTT method, PrestoBlue is not only easy to use and simple to operate but also greatly reduces human error. Moreover, it is also suitable for high-throughput analysis. If the price could be cheaper, it would be perfect!

Great product. Fast, robust and versatile.
Cell proliferation or viability assay of epithelial cells
I use PrestoBlue for cell proliferation assays of different kind of epithelial cells. I use different cell lines and treat those with different agents. I always needed a quick approach which can be fast as well. PrestoBlue is a great product with the advantages of other similar products. I will always use it and I highly recommend this product to every one.

PrestoBlue is a ready to use cell permeable resazurin-based solution that functions as a cell viability indicator by using the reducing power of living cells to quantitatively measure the proliferation of cells. When added to cells, the PrestoBlue reagent is modified by the reducing environment of the viable cell and turns red in color, becoming highly fluorescent. This color change can be detected using fluorescence or absorbance measurements. The PrestoBlue Cell Viability Reagent allows you to:
- Save time with an incubation step as short as 10 minutes
- Obtain high quality results with a large dynamic range
- Experience convenience with the add and read homogenous format
- Monitor living cells and perform downstream functional assays 10-minute incubations
The PrestoBlue Cell Viability Reagent is the only live-cell viability reagent on the market able to provide robust data typically in as little as 10 minutes following reagent addition. All other resazurin-based cell viability reagents on the market require a one to four hour incubation with the reagent prior to obtaining data. High quality results based on the cell type and incubation time, PrestoBlue Cell Viability Reagent can detect as few as 12 cells per well in a 384 well plate. After ten minutes of incubation the PrestoBlue Reagent can linearly detect cells down to 98 cells⁄well with a Z’ value of greater than 0.5.
Homogenous assay format
The PrestoBlue Cell Viability Reagent is an addition-only reagent. Without the cell lysis or solubilization steps required by other assays on the market, hands-on time is minimized.
Live cell assays
The PrestoBlue Cell Viability Reagent does not require cell lysis. Cells may be incubated for up to 24 hours in the presence of PrestoBlue Cell Viability Product. Simply remove the reagent from the cells and replace it with growth medium for further proliferation.
