Abstract :
[en] Nowadays, physiological amino acids profiling is based primarily on ion exchange chromatography (IEC) coupled to a post-column derivatization with ninhydrin and UV detection at two wavelengths. Unfortunately, this technique suffers various drawbacks such as long analysis time, high sample volume and specific costs related to the maintenance of a dedicated equipment. These reasons have led us to consider a technology switch to a mass spectrometry method. We tested the kit aTRAQ amino acids analysis for physiological samples (AB Sciex), offering a selective quantification of more than 40 amino acids, and have implemented the acquisition of various original markers to the initial method. The accuracy profiles established for each amino acid show that the results are very reliable. The linearity is assured between 1 and 1.000 mumol/L for most analytes. Result comparison with IEC method showed good agreement. Reference ranges are similar to those defined for the IEC method and patients with inborn errors of metabolism were readily identified. The aTRAQ method offers a valid alternative to IEC method with several advantages: reduced sample volume, decreased run time and increased specificity. However, the procedure requires a thorough review of all chromatographic peaks, process that considerably lengthens the overall time of the procedure. Finally, financial and practical considerations of both techniques have to be counterbalanced before initiating any methodological transition.
