“timsTOF: Stop Compromising & have it all! – Throughput, Sensitivity, PTMs, Imaging, and Robustness”

Abstract:

Abstract: Trapped Ion Mobility on the timsTOF enables you to find more proteins, faster and with less sample than ever before with enhanced DDA and new DIA approaches using parallel accumulation and followed up with serial fragmentation (PASEF). Throughput is now primed for clinical research cohorts. New SpatialOMx workflows on the timsTOF fleX mean you can image molecules on a tissue section and run a deep coverage LC-MS/MS analysis from the same sample, and on the same instrument.

Speaker 2: Ying Ge, PhD

“New Strategies in Top-down Proteomics for Precision Medicine”

Abstract:

Abstract: Transformative insights from a holistic approach at the systems level have great potential to elucidate disease mechanisms and to develop new therapeutic treatments for precision medicine. Proteomics is essential for deciphering how proteins interact as a system and for understanding the functions of cellular systems in human diseases. However, the unique characteristics of the human proteome, which include the large dynamic range of protein expression and the extreme complexity resulting from a plethora of post-translational modifications (PTMs) and sequence variations, make such analyses difficult. The top-down mass spectrometry (MS)-based proteomics, which is based on analysis of intact proteins, is arguably the most powerful method to comprehensively characterize proteoforms that arise from genetic variations, alternative splicing, and PTMs. My group has made significant advances in top-down MS for analysis of large intact proteins purified from complex biological samples including cell and tissue lysate as well as body fluids. Recently, we are employing a multi-pronged approach to address the challenges in top-down proteomics in a comprehensive manner by developing new MS-compatible surfactants for protein solubilization, novel materials and new strategies for multi-dimensional chromatography separation of proteins, novel nanomaterials for enrichment of low-abundance proteins, as well as a new comprehensive user-friendly software package, MASH Explorer for top-down proteomics. In this talk I will present our recent technology developments in top-down high-resolution mass spectrometry-based proteomics as well as its application to pharmaceutical research, cardiac systems biology and precision medicine.

“Is Structures for Lossless Ion Manipulation (SLIM) a One Trick Pony or a One Stop Shop for Ion Mobility-Mass Spectrometry Analysis?”

Abstract:

Abstract: Since its introduction in 2014, SLIM has been used to demonstrate unprecedented levels of ion mobility resolution and the potential impact of this resolution on both the depth and throughput of analysis.Integration has focused on the combination of high-resolution ion mobility (HRIM) with high resolution mass spectrometry (HRMS) in the form of time of flight instrumentation. This system configuration provides broad spectrum acquisition along with fast analysis times, making it most suitable for discovery or characterization analyses where the goal is to see “everything” with as much specificity as possible.

Researchers at MOBILion have been working to evolve SLIM functionality to also support targeted applications where the goal is instead to focus on a certain number of analytes, but to be able to detect them as accurately and sensitively as possible, even within complex biological matrices. This presentation will provide an overview of these various designs of the SLIM and show how this platform technology can be tailored to enhance the performance of all types of mass spectrometric detection.

PhD, Associate Professor of Chemistry and Pharmaceutical Science at Northeastern University's Barnett Institute

“Top-down- and ion mobility MS-enabled drug discovery for ALS”

Abstract:

Abstract: We have employed top-down MS to discover ALS-related structural changes to SOD1, an ALS-associated protein. Topics will include custom-made antibodies to purify SOD1 (which can cause ALS) from ALS patients; using ultrahigh resolution MS to determine the sites of PTMs and how these modifications effect SOD1 higher-order structure; determining which modifications are disease-relevant using neurotoxicology assays; and the development of a novel, privileged chemistry using modified cyclic disulfides, for preventing oxidative PTMs and stabilizing proteins.

“Mass Spec Approaches to Supporting Biologic Development”

Abstract:

Abstract: Monoclonal antibodies (mAbs) have become the most common modality for Biopharma therapeutic research programs. Years of research and development are required to identify the best candidate to move forward into clinical trials. Along the way, many analytical assays are used to screen, characterize and quantify these biomolecules. Traditionally, immunoassays such as ELISA (enzyme-linked Immunosorbent assay) have been the preferred analytical method, but more techniques have been stepping up to the challenge. Since the unique critical reagents required for ELISA can take months to generate, analytical techniques that take less method development time can have an “early-adoption” advantage that speeds up critical decision-making. Among them, LC-MS is the most appealing due to the accuracy, sensitivity, and specificity achieved by it.

In this presentation, we will discuss workflows to aid in the development, characterization and quantitation monoclonal antibodies. Shimadzu’s Cell Culture Media analysis provides bioprocess development scientists a 125-component snapshot in a single 17-minute LCMSMS method. Coupled with Protein Metrics Byos software, Shimadzu’s 9030 LCMS-QToF can provide an in-depth assessment of a mAb’s overall composition. Finally, Shimadzu’s nSMOL immunocapture kit for the quantitation of traditional mAbs, biosimilars, and hybrids by LC-MS/MS. Along with the nSMOL kit, the Ultra Fast scanning (30000 u/sec) and extreme sensitivity of the Shimadzu LCMS-8060 system allows for the detection of many CDR peptides from a single mAb or even for multiplexed samples in a single analytical run. The minimal method development time of nSMOL coupled with mass spectrometry can be a game-changer for mAb analysis in a high-throughput laboratory.

“Leveraging the timsTOF Pro Platform to Interrogate the Functional Proteome”

Abstract:

Abstract: Despite the growing use of mass spectrometry in biomedical research, the wide dynamic range of protein expression and varying stoichiometry of post-translational modifications represent a significant hurdle to achieving ‘unbiased’ proteome characterization. These limitations also impede our ability to identify and characterize new protein drug targets. In this presentation I will discuss our recent efforts to leverage the unique analytical performance of the timsTOF Pro platform to interrogate multiple aspects of the functional proteome. Examples will include deep proteome coverage of highly enriched, primary human cells, analysis of post-translational modifications, characterization of selective small molecule inhibitors, as well as our initial efforts to develop parallel reaction monitoring (PRM) acquisition on the timsTOF Pro for biomarker validation.

“Direct Detection and Quantification of Neo-antigens”

Abstract for Qing Wang:

Abstract: Many immunotherapeutic approaches under development rely on T-cell recognition of cancer-derived peptides bound to human leukocyte antigen molecules on the cell surface. Direct experimental demonstration that such peptides are processed and bound is currently challenging. Here we described a method that meets this challenge. The method entailed an optimized immuno-precipitation protocol coupled with two-dimensional chromatography and mass spectrometry. The ability to detect and quantify minute amounts of pre-defined antigens should be useful for both basic research in tumor immunology as well as for the development of rationally-designed cancer vaccines.

“Cancer Mechanisms and Profiling from Analysis of AP/MS and Shotgun Proteomics”

Abstract for Peter Jackson:

One fifth of human cancers contain mutations activating the Ras GTPases, but no targeted therapies are yet available. Many effectors of the Ras pathway and potential targets remain underexplored and we have limited understanding of numerous paralogs of Ras effectors and other redundancies that contribute to Ras tumor growth. Here, we produce a multiomic map of the Ras function in lung adenocarcinoma. We use affinity purification mass spectrometry (AP/MS) to generate a protein-protein interaction (PPI) network. From this network, we constructed a sgRNA library covering 120 Ras pathway genes and screened for genetic interactions (GIs) by CRISPR dual knockout. We find new effectors of Ras-driven cellular function, and over 250 synthetic lethal GIs, presenting new candidate single and combination therapeutic targets. We identify important synergies between Ras and Rap signaling and between their downstream effector pathways. Our recent studies have used selective covalent inhibitors of a KRAS-G12C allele from the Shokat lab to address global signaling changes by shotgun proteomics, using the Bruker timsTOF. I will present the latest technical details for our data and also outline our informatics pipeline, which provides critical validation of our MS findings. These discoveries illustrate the power of multiomic interaction-mapping approach and may be applied to analyze a range of human diseases or other biological systems.

“New Dimensions in Confidence for OMICS and HCPs with TIMS Technology”

Abstract for Tharan Srikumar:

Confidence in mass spectrometry measurements is key for advancing drug discovery projects. Bruker provides a comprehensive line of ESI and MALDI TOF instruments as well industry leading ultrahigh resolution MRMS systems and the evolutionary timsTOF Pro. The timsTOF Pro with PASEF relies on a unique dual Trapped Ion Mobility Spectrometry (TIMS) front end to provide nearly 100% duty cycle with no loss of ions. When combined with the Parallel Accumulation Serial Fragmentation (PASEF) method, the timsTOF Pro with PASEF enables sequencing speeds in excess of 100 Hz, and significant improvements in sensitivity. Powered by TIMS, the instrument provides separation for simple isomers and conformers and stands as an integrated part of 4D omics workflows because of the accurate and reproducible collisional cross-sections (CCS) values for all peptides. Recently, the TIMS technology has been applied to host cell protein (HCP) analysis of mAbs with record speed and depth. Newly announced diaPASEF enables more ways to accurately quantify proteins. The presentation will show how the technology can benefit HCP analysis and OMICS to step up the research to the next level.

“Quantitative Proteomics for Understanding the Epigenetic Cancer Code”

Abstract for Prof Garcia:

Histones are small proteins that package DNA into chromosomes, and a large number of studies have showed that several post-translational modification (PTM) sites on the histones are associated with both gene activation and silencing. Along with DNA and small non-coding RNA, histone PTMs make up epigenetic mechanisms that control gene expression patterns outside of DNA sequence mutations. Dysregulation of these chromatin networks underlie several human diseases such as cancer. Here I will give an update on technology advancements that have allowed for high-throughput quantitative analyses of histone PTMs and chromatin structure, and how we are applying these methods to understand epigenetic reprogramming found in malignant peripheral nerve sheath tumors (MPNSTs). MPNST is an aggressive sarcoma with recurrent loss of function alterations in polycomb-repressive complex 2 (PRC2), a histone-modifying complex involved in transcriptional silencing.

Speaker 2: Prof Vicki Wysocki

The Ohio State University

“Native Mass Spectrometry and Surface-Induced Dissociation: Characterization of Protein and Nucleoprotein Complexes”

Abstract for Prof Wysocki:

Characterization of the overall topology and inter-subunit contacts of protein complexes, and their assembly/disassembly and unfolding pathways, is critical because protein complexes regulate key biological processes, including processes important in understanding and controlling disease. Tools to address structural biology problems continue to improve. Native mass spectrometry and associated technologies are becoming an increasingly important component of the structural biology toolbox. When the mass spectrometry approach is used early or mid-course in a structural characterization project, it can provide answers quickly using small sample amounts and samples that are not fully purified. Integration of sample preparation/purification with effective dissociation methods, ion mobility, and computational approaches provide a MS workflow that can be enabling in biochemical, synthetic biology, and systems biology approaches. Beyond what MS can provide as a stand-alone tool, MS can also guide and/or be integrated with other structural biology approaches such as NMR, X-ray crystallography, and cryoEM. MS can determine whether the complex of interest exists in a single or in multiple oligomeric states and can provide characterization of topology/intersubunit connectivity, and other structural features. Examples will be presented to illustrate the role MS and surface-induced dissociation can play in guiding a structural biology workflow and will include designed protein complexes and isolated or recombinant protein and nucleoprotein complexes.

“Improving Biomarker Assay Workflows by Ensuring Reagent Quality using LC-MS Characterization”

Abstract for Scott A. Robotham:

The success of any assay is heavily dependent on the reagents used. For most assays this involves reagent antibodies, but in the case of biomarker assays recombinant proteins that act as a reference material for method development and QC are reagents that must be generated and characterized. Ensuring the quality of this reference protein is critical to the assay development, however oftentimes the only QC performed on these calibrator proteins is gel shift assay, which while useful only confirms if a protein is relatively close to the correct expected molecular weight. In order to provide a more accurate results, our group has utilized intact mass analysis to confirm amino acid sequences of calibrator proteins allowing for better quality control (QC) of these regents. In addition to this we have recently started to apply bottom-up proteomics techniques to our biomarker analysis in an effort to get additional information about these calibrator proteins. In this talk, two examples of how we are leveraging bottom-up to improve our reagent biomarkers workflows will be highlighted. The first example will explain how we are using proteomics to obtain sequence information for calibrator proteins that have amino acid sequences that are uncertain. For the second example our ongoing efforts to couple proteomics with immunocapture in order to characterize endogenous biomarkers will be discussed.

“Expanding Accessibility to High Performance LCMS Analytics in Biopharma: From Molecular Characterization to Attribute Monitoring”

Abstract for Weibin Chen:

Mass spectrometry (MS) has long been an enabling technology in the regulatory definition of a well‐ characterized biotherapeutic protein. It is an invaluable tool to characterize molecular structures, assess process variabilities, and monitor the critical quality attributes of biotherapeutics – but until just recently has it been made accessible to biochemists. Recent advances in LC, MS and informatics technologies are transforming biotherapeutic analyses, not only in terms of the quality of analytical data, but also in their accessibility for biochemists to generate, capture, and harness top‐quality LC/MS information to enable faster decision making.This talk will focus on how the evolving requirements of biotherapeutic analysis are addressed using modern LCMS analytical workflows built upon the recent introduced BioAccord system, and on how the leading separation, spectrometric, and informatics technologies are expanding the range of analytical challenges that MS workflows can routinely address while maintaining data integrity. We will provide several case studies on a panel of monoclonal antibodies (mAbs) for routine characterization and product quality attributes monitoring, and highlight how a workflow‐driven approach can produce time‐of‐flight mass spectrometry data that is not only highly comparable in quality to more complex advanced MS instruments, but that is more available to non‐traditional MS users in biopharmaceutical development and manufacturing organizations.
