ProteomicsExperimental strategies to improve drug-target identification in mass spectrometry-based thermal stability assays
In this study, we developed a model system for the assessment of small molecule-protein interactions using intact cells treated with a commercially available highly specific mitogen-activated protein kinase (MEK) 1/2 inhibitor to prepare a set of unfractionated test samples labeled with tandem mass ...

ProteomicsExperimental strategies to improve drug-target identification in mass spectrometry-based thermal stability assays
Mass spectrometry (MS)-based thermal stability assays have recently emerged as one of the most promising solutions for the identification of protein-ligand interactions. Here, we have investigated eight combinations of several recently introduced MS-based advancements, including the Phase-Constraine...

ProteomicsEvaluation of a modified Orbitrap Astral Zoom prototype for quantitative proteomics - Beyond identification lists
Mass spectrometry instrumentation continues to evolve rapidly, yet quantifying these advances beyond conventional peptide and protein detections remains challenging. Here, we evaluate a modified Orbitrap Astral Zoom mass spectrometer (MS) prototype and compare its performance to the standard Orbitra...

ProteomicsEvaluating the Performance of the Astral Mass Analyzer for Quantitative Proteomics Using Data Independent Acquisition
We evaluate the quantitative performance of the newly released Asymmetric Track Lossless (Astral) analyzer. Using data independent acquisition, the Orbitrap Astral mass spectrometer quantifies 5 times more peptides per unit time than state-of-the-art Orbitrap mass spectrometers, which have long been...
