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.

A high performance liquid chromatography–ultraviolet (HPLC–UV)-based method was recently developed for the quantification of selpercatinib in human plasma, an advance that may lead to the reduction of adverse events as well as an optimization of efficacy.

Following the HPLC 2024 Conference in Denver, Colorado, LCGC International spoke with Anne Marie Smith of ACD/Labs about the new ICH Q14 guidelines and how they impact analytical scientists and their work.
