[A quantitative analysis of amino acids in blood serum by isocratic reverse-phase HPLC].
A method for chromatographic analysis of human serum amino acids is proposed. Orthophthalic aldehyde in combination with 2-mercaptoethanol or sodium sulfite as a reagent for amino acid transfer into derivatives permits the identification of 15 amino acids within the framework of a single chromatographic system with an isocratic elution regimen. Glutamic acid, asparagine, serine, glutamine, histidine, taurine, alanine, arginine, methionine, isoleucin, ornithine, leucin, phenylalanine, lysin, and triptophane were measured in the sera of healthy donors and patients with ischemic stroke.
