Applications: A highly sensitive tetrazolium reagent that produces a water-soluble formazan (orange color that absorbs at 460 nm) in NADH. It is newer generation formazan-based dyes which release the converted product into the medium in a soluble form allowing for a non-destructive determination of viability enabling the cells to be subject to further investigations
