A Tandem LC Workflow for Maximizing Mass Spectrometer Utilization in Proteomics

The sample throughput of high-sensitivity liquid chromatography-mass spectrometry (LC-MS) based proteomics analysis is restricted by the pressure limitations of LC and column hardware, with some methods wasting as much as 50% of the method cycle time outside of MS acquisition.
Traditional routes for boosting throughput include shorter columns and gradients, higher flow rates, and using trap-and-elute workflows – all of which introduce trade-offs in sensitivity and proteome depth.
The Thermo Scientific™ Vanquish™ Neo tandem direct injection workflow leverages hardware innovations and software intelligence to eliminate method overhead while maintaining data quality across nano, capillary, and micro-flow LC-MS.
In this webinar experts from Evotec and Bayer will showcase how they implemented the tandem direct injection workflow for their proteomics work. Dr. Nagarjuna Nagaraj will present on how Evotec is using tandem direct injection with nano-LC columns packed in-house to boost sample throughput of their chemoproteomics screening pipeline, while Dr. Alexander Boychenko from Bayer will discuss how his lab is using a micro-flow tandem direct injection approach to analyze plasma samples for translational proteomics.

Presenter: Dr. Nagarjuna Nagaraj (Group Leader High Sensitivity Proteomics, Evotec)
Dr. Nagarjuna Nagaraj is a proteomics group leader at Evotec focusing on high sensitivity and high throughput proteomics applications with more than 18 years of experience in proteomics and mass spectrometry. Nagarjuna obtained his PhD from the Matthias Mann lab focusing on sample preparation and MS data acquisition strategies for clinical applications. After a postdoc he directed the mass spectrometry core facility at the Max-Planck-Institute of Biochemistry working on a wide range of protein and peptide mass spectrometry projects such as bottom-up proteomics, structural mass spectrometry including HDX, native and crosslinking MS, intact protein and small molecule analysis.
Presenter: Dr. Alexander Boychenko (Head of R&D Laboratory Precision Medicine Markers, Bayer)
Alexander Boychenko is leading Omics Research within the Translational Sciences team of the Pharmaceuticals division at Bayer Group. He is focused on implementing innovative analytical technologies and developing novel methodologies for proteomics, metabolomics, and ligand-binding assays (LBA) to comprehensively characterize human and animal model phenotypes, enabling disease understanding and novel biomarker discovery. He holds a Ph.D. in Analytical Chemistry from Kharkiv National University, Ukraine. During his post-doctoral work at the University of Groningen, The Netherlands, he combined LC-MS and immunoassays to discover and validate protein biomarkers in biofluids for cancer screening. Before joining Research and Early Development at Bayer AG, he developed and introduced new liquid chromatography-mass spectrometry products at Thermo Fisher Scientific. Alexander is a subject matter expert in LC-MS, biological data interpretation, and precision medicine. He utilizes his passion for applying technical expertise to develop new medicines.
Presenter: Dr. Alec Valenta (Product Marketing Manager, Thermo Fisher Scientific)
Alec is the product marketing manager for the Vanquish Neo UHPLC system and low-flow LC columns. Prior to joining Thermo Fisher Scientific he earned his PhD in analytical chemistry from the University of Michigan where he helped advance microdialysis sampling of neurochemicals and developed LC-MS methods to quantify small molecule neurotransmitters, neuropeptides, and metabolites in a variety of complex biological samples.
