title: Rapid method for the separation and detection of tissue short-chain coenzyme A esters by reversed-phase high-performance liquid chromatography.
abstract: A simple and rapid method for the separation and identification of tissue levels of short chain coenzyme A (CoA) esters by a reversed-phase high-performance liquid chromatography with ultraviolet-visible adsorbance detection is described. Samples of liver, heart and kidney tissues were homogenised in 5% sulfosalicylic acid containing 50 microM of dithioerythritol in 1:9 w/v proportion. Following centrifugation, 20 microliters of the supernatant were directly injected onto a 3-micron ODS C18 column (100 x 4.6 mm I.D.). The separation of acetyl-CoA, malonyl-CoA, methylmalonyl-CoA, succinyl-CoA, propionyl-CoA and free CoASH was achieved in less than 20 min using gradient elution with sodium phosphate, sodium acetate and methanol at a constant flow-rate of 1.5 ml/min. The lowest detection limit was 3 pmol.
