Method P.1325 left column top paragraph: "...[investigators] developed a new method that combines rapid immunocapture of epitope-tagged mitochondria with metabolite profiling by liquid chromatography and mass spectrometry (LC/MS)."
Comments P.1326 left column: "Both the enzyme citrate synthase (CS) and the metabolite coenzyme A (CoA) predominantly reside in the mitochondrial matrix, with only 10%–20% of cellular CoA being extra-mitochondrial (primary sources)." 1st primary source studied rat heart
