Standard curve for the quantification of the CoQ pool size by LC-MS/MS

Representative standard curve or oxidised CoQ9 (a) and CoQ10 (b). The MS response of increasing concentrations of CoQ9 and CoQ10 was compared to 0.5 pmol of d6-CoQ10 (internal standard, IS). Data are mean ± S.D. of 3 replicates. The grey-shaded section of the standard curve on the left is expanded and replotted in the right panel.
