When the last edition of this book was published in 2000, the field of proteomics was in its infancy. Now in its adolescence, proteomics is fundamentally transforming biological and medical research. Much of this transformation can be attributed to technological advancements, particularly in mass spectrometry. As a result of these rapid developments that have led to expanded areas of research and innovative applications, an update to Mass Spectrometry of Proteins and Peptides is not only worthwhile, but arguably mandatory. Spanning fields from microbial forensics and clinical applications to protein structure, dynamics and function, the following chapters written by leading experts serve as a forum for presenting some of the latest revolutionizing methods for mass spectrometry-based characterization of proteins and peptides. Staying faithful to the spirit of the Methods in Molecular Biology(TM) series, all chapters are written in the same format, whereby each chapter opens with a basic description of the method, followed by a description of the protocol and then practical step-by-step instructions to ensure experimental success. * Mass Spectrometry of Proteins and Peptides: Methods and Protocols, Second Edition* is a valuable resource for novice and seasoned practitioners in the fields of biochemistry, molecular biology, clinical chemistry, immunology, genetic, microbiology and toxicology.
