Rapid assay of cell activity of yeast cells

Yeast cells produce H 2O 2 in the presence of exogenous menadione, and the extracellular concentration of H 2O 2 produced is proportional to the viable cell number or cell activity. Chemiluminescent assay of menadione-catalyzed H 2O 2 production requires only a few minutes, and is useful for rapid d...

Zusammenfassung:	Yeast cells produce H 2O 2 in the presence of exogenous menadione, and the extracellular concentration of H 2O 2 produced is proportional to the viable cell number or cell activity. Chemiluminescent assay of menadione-catalyzed H 2O 2 production requires only a few minutes, and is useful for rapid determination of the viability of yeast cells.
