Qualitative and Quantitative Characterization of Therapeutic Antibody using High Speed and High Resolution Mass Spectrometry

Qualitative and Quantitative Characterization of Therapeutic Antibody using High Speed and High Resolution Mass Spectrometry

23 Dec 2015

Mass Spectrometry has become a critical tool for structural characterization of therapeutic antibodies. Qualitative analysis of intact protein, amino acid sequence, enzymatic peptides, disulfide linkages, carbohydrates and various post translational modifications can be done using high resolution MS and MS/MS data acquisition. For high accurate and high throughput data analysis, we need an optimized data acquisition method and sophisticated data processing tools. This poster demonstrates the optimization of a LC/MS/MS data acquisition method for antibody characterization and established a new data processing pipeline using XICs.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

This parallelization reduces the cost per experiment and increases reproducibility and output volume of data.PeptidesPeptides are short chains of amino acids that play key roles in biological processes, including signaling, immune responses, and enzyme regulation. Peptide research is critical in drug discovery, diagnostics, and vaccine development. Browse our peer-reviewed product directory to find the best peptides and peptide-related products, compare options, check reviews, and get pricing directly from manufacturers.Post-Translational ModificationsTherapeutic AntibodiesTherapeutic antibodies are antibodies engineered for use in treating diseases. They can be designed to target specific antigens, blocking harmful interactions or modulating immune responses. Therapeutic antibodies are critical in treating conditions like cancer, autoimmune disorders, and infectious diseases.
