Racing Against Time: High-Throughput Analysis of Dermorphin in Equine Urine

LCGC International sat down with Jose Bernal to discuss his latest research in using pyrolysis gas chromatography–mass spectrometry (Py-GC–MS) and other chromatographic techniques in studying microplastics in food analysis.

In this column, we discuss the label-free and stable isotope labeling proteomics approaches that help in biomarker discovery. We also discuss the different enrichment techniques, such as stable isotope labeling by amino acid in cell culture (SILAC), isobaric tags for relative and absolute quantitation (iTRAQ), and tandem mass tags (TMT, that help in measuring low-abundance protein biomarkers.

LCGC International spoke to Silvia Valverde and Ana María Ares of this group about their research and the resulting article.

Known as “forever chemicals”, PFAS exposure has been linked indirectly and directly to a range of potential health issues. The objective of this study was the development of an optimized sample preparation and LC–MS/MS method for the analysis of PFAS in serum for biomonitoring applications.

Shanghai University of Sport scientists recently developed a doping control method based on gas chromatography combustion isotope ratio mass spectrometry (GC/C/IRMS).
