Oxidation-reduction ratio studies of mitochondria in freeze-trapped samples. NADH and flavoprotein fluorescence signals.
Open accessAbstract
The recording of oxidation-reduction-related fluorescence signals of oxidized flavoprotein (Fp) and reduced pyridine nucleotide (PN) from isolated mitochondria at temperatures below -80 degrees C can be accompanished with a high degree of accuracy and a wide dynamic range. The specific low temperature enhancement of the fluorescence signals due to increased quantum yield and to multiple scattering affords increased accuracy and less interference due to screening pigments such as hemoglobin and myoglobin. Since the metabolic processes are arrested and the recording speed can be greatly diminished, the technique can operate with a much smaller concentration of mitochondria than is needed at room temperature, and the method is suitable for localized oxidation-reduction measurements. The Fp and PN signals originate from the mitochondrial matrix space in which they represent the major fluorochromes. Since Fp and PN are near oxidation-reduction equilibrium, the ratio of the two fluorescence intensities, suitably normalized, approximates the oxidation-reduction ratio of oxidized flavoprotein/reduced pyridine nucleotide. Thus, this technique affords a foundation for the resolution of oxidation-reduction states in two and three dimensions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
