A novel simultaneous determination of native and isotopically-labeled plasma amino acids in pigs by gas chromatography mass spectrometry

An abstract of a study by McGilvray et al developing a method that allows simultaneous quantification of both native and isotopically- labeled AA in plasma and other physiological fluids in pigs is presented. The method utilizes differences in mass between labeled and unlabeled AA. This method provides a fast and easy to use alternative for an accurate measurement of native and isotopically-labeled AA in plasma and other physiological fluids in pigs.
