Optical redox ratio
WebOptical redox ratio has been calculated by taking the ratio of mean fluorescence intensities within the segmented cytoplasm regions as: redox ratio = FAD/(NAD(P)H+FAD). The key … WebThe optical redox ratio was calculated for each pixelastheFAD/(NADH+FAD)TPEFintensity(fig.S1C).Although both NADH and NADPH may have contributed to the signal that we attribute to NADH, we have shown by mass spectrometry that there are negligible levels of NADPH in these cells under these …
