New NIST Method Evaluates Response to Oxidation in Live Cells (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption NMR data showing the levels of reduced glutathione (GSH) and oxidized glutathione (GSSG) over time in yeast cells at rest (top) and under oxidative stress (bottom). The cells at rest have almost no GSSG (dark blue shades) but it spikes briefly when they are stressed, while GSH declines. This type of analysis may one day help to measure cell health.
