Interpreting Protein Mass Spectra is a hands-on laboratory guide for a wide range of researchers investigating the structures of proteins and peptides. The focus is on the interpretation of structural information gathered through electrospray ionization-mass spectrometry (ESI-MS). The book will also provide useful background and protocols for anyone using matrix-assisted laser desorption/ionization (MALDI), fast atom bombardment (FAB), and secondary ion mass spectrometry (SIMS). The book includes numerous practical examples, detailed discussions of experimental setups, and valuable hints for troubleshooting both methods and the handling of materials.
