Invitrogen™ PrestoBlue™ HS Cell Viability Reagent, 25 mL

PrestoBlue HS Cell Viability Reagent is a ready-to-use resazurin-based solution that functions as a cell health indicator by using the reducing power of living cells to quantitatively measure viability. Upon entering living cells, resazurin is reduced to resorufin, a compound that is red in color and highly fluorescent. High background fluorescence caused by various contaminants reduces the performance of resazurin-based reagents. To improve the performance an innovative purification process was developed that removes these contaminants. This highly purified, non-toxic resazurin was used in the standard PrestoBlue formulation, creating the PrestoBlue HS Cell Viability Reagent. Changes in viability can be easily detected using either an absorbance- or fluorescence-based plate reader. The PrestoBlue HS Cell Viability Reagent has been optimized for the fast and reliable detection of mammalian cell viability
