TranscriptomicsSorted tumor RNA-seq of syngeneic murine mutant IDH1 ICC tumor model treated with IDH1 inhibitor against vehicle
IDH1 is the most commonly mutated metabolic gene across human cancers, with the highest mutational frequency observed in AML, glioma, chondrosarcoma, and intrahepatic cholangiocarcinoma. Mutations of the hot spot R132 codon alter the activity of the IDH1 enzyme, resulting in the NADPH-dependent conv...

ProteomicsDynamic Data Independent Acquisition Mass Spectrometry with Real-Time Retrospective Alignment
We report a data independent acquisition (DIA) strategy that dynamically adjusts the tandem mass spectrometry (MS/MS) windows during the chromatographic separation. The method focuses MS/MS acquisition on the most relevant mass range at each point in time – improving the quantitative sensitivity by ...

ProteomicsDevelopment of highly multiplex targeted proteomics assays in biofluids using a nominal mass ion trap mass spectrometer
The development of targeted assays that monitor biomedically relevant proteins is an important step in bridging discovery experiments to large scale clinical studies. Targeted assays are currently unable to scale to hundreds or thousands of targets. We demonstrate the generation of large-scale assay...

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...

ProteomicsA framework for quality control in quantitative proteomics
A thorough evaluation of the quality, reproducibility, and variability of bottom-up proteomics data is necessary at every stage of a workflow, from planning to analysis. We share vignettes applying adaptable quality control (QC) measures to assess sample preparation, system function, and quantitativ...

ProteomicsMag-Net: Rapid enrichment of membrane-bound particles enables high coverage quantitative analysis of the plasma proteome
Membrane-bound particles in plasma are composed of exosomes, microvesicles, and apoptotic bodies and represent ~1-2% of the total protein composition. Proteomic interrogation of this subset of plasma proteins augments the representation of tissue-specific proteins, representing a “liquid biopsy,” wh...

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...
