Analysis of CoQ₉and CoQ₁₀pools in murine tissue.A and B, representative HPLC traces for CoQ analysis from murine heart and brain (A) and liver (B). In the liver, the presence of another substance that co-migrated with CoQ₉ and CoQ₁₀H₂ led to residual peak intensity following reduction and oxidation, respectively and precluded quantitative analysis. C and D, concentrations of oxidized, reduced, and total CoQ₉ (C) CoQ₁₀ (D) in murine heart and brain. E, redox ratio of the two CoQ pools. n = 5 in all experiments.
