alamarBlue reagent and PrestoBlue reagent contain resazurin in a proprietary stabilizing formulation that allows for a convenient “mix, incubate, and read” protocol. PrestoBlue reagent is an improvement in the formulation of alamarBlue reagent that allows for much faster staining (typically 10 minutes vs. 1-4 hours to obtain a similar signal and sensitivity). C12-resazurin is a derivative of resazurin that has better cellular retention and thus allows for analysis on a flow cytometer and multiplexing with viability indicators and other biomarkers.
