| Notes | A 100 ng/mL standard mix of 22 acylcarnitines and 13 amino acids was prepared in 85:15 acetonitrile:water (v/v) that was fortified with known concentrations of stable isotope-labeled internal standards. The solution was vortexed at 3000 rpm for 10 seconds to mix, and then the supernatant was injected for LC-MS/MS analysis. |
