Invitrogen™ LIVE/DEAD™ Yeast Viability Kit

The LIVE/DEAD™ Yeast Viability Kit combines a novel two-color fluorescent probe for yeast viability, FUN™ 1, with a fluorescent fungal surface labeling reagent Calcofluor™ White M2R. Plasma membrane integrity and metabolic function of fungi are required to convert the yellow-green-fluorescent intracellular staining of FUN™ 1 into red-orange intravacuolar structures; Calcofluor White M2R labels cell-wall chitin with blue-fluorescence regardless of metabolic state.
