Biochemicals

Storage: -20°CShipping: Blue Ice

A next generation tetrazolium reagent that serves as a sensitive chromogenic indicator for NADH. It is reduced by NADH at neutral pHs in the presence of 1-methoxy PMS to produce the corresponding formazan dye that absorbs at 460nM. Useful in cell proliferation assays as a cell viability indicator.
