Amino acid analysisHPLCPlasma amino acids are usually analyzed by ion-exchange chromatography (IEC), a reproducible but time consuming method. Here, we test whether plasma amino acids can be analyzed using reverse-phase high performance liquid chromatography (HPLC). Filtered plasma, with S-...
The same method was also used for (a) the assay of free primary amino acids in umbilical bloods, (b) the efflux of amino acids from isolated human placental villus, and (c) to study the uptake of 伪-aminoisobutyric acid (AIB), a non-metabolizable amino acid, by the isolated placental...
Rapid analysis of amino acid phenylthiohydantoins by high-performance liquid chromatography. All 20 amino acid phenylthiohydantoins (PTHs) can be separated in a single analysis in less than 20 min using a 25 脳 0.46-cm DuPont Zorbax ODS column deve... CL Zimmerman,E Appella,JJ Pisano - ...
