title: [Quantitative gas chromatographic determination of 3-methylhistidine in biological fluids].
abstract: The gas chromatographic procedure is suggested to determine 3-methylhistidine in biological fluids. The amino acid fraction containing 3-methylhistidine is separated by ion-exchange chromatography. Amino acids are transformed into N-trifluoroacetyl-O-isobutyl esters which are analyzed by the gas chromatography instrument with micropacked columns and ionization-resonance detector. The limit of the quantitative determination of 3-methylhistidine is 50 ng per a probe.
