Additional file 5 of Comparison between 5 extractions methods in either plasma or serum to determine the optimal extraction and matrix combination for human metabolomics

Additional file 5: Table S1. List of isotopic unlabeled and labeled standard analytes. Following information include specifications, stock solution concentrations stored at -80°C, and final solution preparations for each standards. Different final concentrationsare diluted in five solvents, acetonitrile, 0,1% formic acid/methanol, and 0,1% formic acid/acetonitrile) for each standards. A calibration curve is then created for the assessment of linearity, sensitivity and matrix effects. MI : 7 labeled standard mixed; MII : unlabeled organic acid commercial mix.
