Invitrogen™ PrestoBlue™ and PrestoBlue™ HS Cell Viability Reagents

Monitor cell proliferation and viability with the resazurin-based PrestoBlue and PrestoBlue HS cell viability reagents. These nontoxic and cell permeable reagents quantitatively measure cell viability in as little as 10 minutes using absorbance- or fluorescence-based microplate readers.

PrestoBlue and PrestoBlue HS cell viability reagents are ready-to-use, nontoxic, resazurin-based solutions that function as long term kinetic cell health indicators for fluorescence and absorbance-based microplate assays. These reagents are cell permeable and use the reducing power of living cells to quantitatively measure cell proliferation and viability in as little as 10 minutes. PrestoBlue HS Cell Viability Reagent is an improved version of PrestoBlue reagent, containing highly purified resazurin, which increases sensitivity and reduces background in cell proliferation assays. Add the power of multiplexing with reagents such as the CyQUANT Direct assay to improve your data analysis.
