Responsibilities: Mass Spectrometry & Biophysics Based in Rahway, NJ the Mass Spectrometry & Biophysics (MSB) team is an integral part of the Computational & Structural Chemistry Department within Discovery Chemistry. Working across all therapeutic areas & supporting teams at all network sites we focus our efforts in 3 principal areas to drive end-to-end pipeline impact: 1. Screening & Hit-to-Lead. Discovery & optimization of ligands across the modality spectrum (fragments, small molecules, bifunctional degraders, peptides, therapeutic proteins) to identify leads that modulate our targets of interest. 2. Elucidating Mode of Interaction. Detailed characterization of how our ligands interact with and modulate our targets of interest at the molecular level. 3. Understanding Mechanism of Action. Determining how perturbing our targets of interest affects disease pathology both in vitro and in vivo. To achieve all of the highlighted activities, our team combines state-of-the-art capabilities and expertise in 4 key areas. We collaborate closely with project teams to craft a holistic approach appropriate for each program & question at hand: * Protein Biochemistry. We provide carefully designed, high-quality and thoroughly characterized proteins for screening and assay development. Leveraging our expertise across target classes (including integral membrane proteins & multi-subunit complexes) and utilizing both internal & external resources we partner directly with teams to produce proteins that are qualified for even the most challenging applications. * Biophysics & Biochemistry. Using a toolbox of techniques including SPR, fluorescence/CD spectroscopy, calorimetry, nano-DSF & radioligand binding we perform detailed thermodynamic & kinetic profiling of protein-ligand interactions across all modalities. * BioNMR. Our capabilities in high-resolution NMR spectroscopy enable us to rigorously study the solution behavior of proteins (including excipient and self-association effects) and to conduct detailed experiments probing molecular interactions using both ligand- and protein-detected techniques. * Mass Spectrometry. We specialize in biophysical mass spectrometry including HDX-MS for protein characterization, binding site mapping and epitope/paratope determination; metabolic flux as a readout for pharmacodynamics and pathway engagement in physiologically relevant settings (both in vitro and in vivo); and ultrahigh-throughput mass spectrometry where we have partnered with groups across the network to enable screening, chemical reaction profiling and protein engineering. * Our overarching goal is to work directly with teams to accelerate the discovery and characterization of molecules on the path to delivering meaningful therapies to patients. Core responsibilities: * Run routine radioligand binding assay protocols, analyze data & generate weekly reports, carry out tissue culture and cell-based binding assays. * Fully document all experiments in our electronic laboratory notebook.
