A protocol to efficiently assess Reactive Oxygen Species (ROS) levels in yeast cells using H2DCF-DA is described here. This method employs lithium acetate to permeate the cell wall, and thus, augments the release of the fluorescent product, dichlorofluorescein from the cells. This protocol obviates the need for both physical and enzymatic lysis methods that are arduous and time consuming. This method is simple, less time consuming and reproducible, especially while dealing with a large sample size. The lithium acetate method gave significantly reproducible and linear results (P < 0.0001), as compared with direct measurement (P = 0.0005), sonication (P = 0.1466) and bead beating (P = 0.0028).
