RP-LC of Phenylthiocarbamyl Amino Acid Adducts in Plasma Acetonitrile Extracts: Use of Multiple Internal Standards and Variable Wavelength UV Detection (Med Worm)

We present here a modified reversed-phase LC of phenylthiocarbamyl amino acids
in plasma deproteinated by the organic solvent acetonitrile. Specificity was
monitored by UV-photodiode array detection and accuracy was controlled by a
plasma spiking procedure with three internal standards. A dual-wavelength
spectrophotometry (254, 283 nm) was used to quantify coeluting ornithine and
tryptophan adducts. The method is simple and economical and enables the
measure of most plasma amino acids for clinical research, also during
therapeutic drug monitoring. Dual UV-fluorimetric detection solutions can
improve its sensitivity. (Source: Springer protocols feed by Protein Science)
