Get high quality cell viability results in as little as 10 minutes with PrestoBlue™ Cell Viability Reagent

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.

PrestoBlue™ reagent is significantly faster than other resazurin-based reagents like alamarBlue® and Cell-Titer Blue® reagents.

PrestoBlue™ reagent only requires a 10-minute incubation period, whereas alamarBlue® and CellTiter-Blue® recommend a 1 to 4 hours incubation. The figure on the right demonstrates the difference in fluorescence signal obtained from PrestoBlue®, alamarBlue®, and CellTiter-Blue® reagents following a 10-minute incubation. The dynamic range is significantly greater at the early time points for PrestoBlue™ reagent.
