alamarBlue Graphic
Fig 1. AlamarBlue is a non-toxic, cell-permeable compound that functions as a cell health indicator. The active ingredient, resazurin, is blue in color and has low fluorescence. As the compound enters living cells, resazurin is reduced to resorufin (conversion of NADH to NAD+) which is a red/pink color with high fluorescence.
