Their high efficacy, safety, and ability to treat life-threatening diseases such as cancer, inflammation, and genetic disorders have revolutionized modern medicine. This is primarily due to advances in recombinant DNA technology that have provided the means to produce therapeutic proteins. However, there are significant challenges in characterizing protein therapeutics, including heterogeneity associated with post- translational modifications, protein conformational dynamics upon modifications, and the complexity in analysis due to the presence of biological matrices. Mass spectrometry (MS) is one of the most highly utilized analytical techniques in the characterization of protein therapeutics because of its unique analytical sensitivity, selectivity, and specificity. Advances in ionization methods including electrospray ionization and matrix-assisted laser desorption ionization, the improvement of MS instrumentation, and the growth in the data processing have greatly contributed to wide applications of MS in biopharmaceutical research and development. I am delighted to bring together the work of contributors from academia and industry in highlighting current analytical approaches and industry practices for the characterization of protein therapeutics using MS. The book begins with an overview on protein MS (Chap. 1), followed by descriptions of quantitative analysis of therapeutic peptides and proteins in biological matrices (Chaps. 2, 3). Structural characterization of protein therapeutics is discussed in Chaps. 4–6 with the focus on modifications of protein therapeutics from discovery to development. A unique class of protein therapeutics, antibody–drug conjugates, is also described in detail (Chap. 7). The remaining chapters (Chaps. 8–10) cover emerging MS techniques for the characterization of protein therapeutics, including hydrogen/deuterium exchange MS, fast photochemical oxidation of proteins, and ion mobility MS. I would like to acknowledge the special efforts and patience of all the authors, who have made significant contributions to this book.

In particular, the invention of matrix-assisted laser desorption/ionization (MALDI) [1] and electrospray ionization (ESI) technologies [2, 3] allows one to measure protein molecular weights and sequences, and to probe conformations and post- translational modifications of proteins. In addition, the mass range of species ame- nable for MS analysis has increased, enabling the transfer of ionized non-covalent species with masses well over one million (e.g., 1.5 MDa 24-Mer flavoprotein vanillyl-alcohol oxidase (VAO) from Penicillium simplicissimum [4] into the gas phase). These advances moved MS into the range of intact protein oligomers and functional machineries. This chapter serves as an introduction to protein MS. As it is a broad topic with a vast literature coverage [5–17], we first introduce spray- and laser-based protein ionization techniques used for protein ionization, beginning with an introduc- tion on the historical development of protein ionization methods, followed by the description of several methods including their principles, strengths, and analytical applications. In addition, we also survey various ion activation methods used for protein/peptide structure analysis (viz. tandem mass spectrometry), including col- lision-, photon-, surface-, and electron-based ion dissociation strategies.
