Second, to increase the mass measurement accuracy and protein identification confidence in FTICR-MS, we have developed a new calibration method, Calibration Optimization on Fragment Ions (COFI), for fragmentation data to correct the effects of space charge in FTICR-MS. There is a post-data processing strategy, and no need to include an internal calibrant or to apply ion population control. COFI has been successfully applied to different types of LC-FTICR fragmentation data, including LC-MS/MS data and multiplexed LC-CID data.

Driven by the widespread growth of proteomic practices, protein separation techniques have been refined to minimize variability, optimize particular applications, and adapt to user preferences in the analysis of proteins. Separation Methods in Proteomics provides a comprehensive examination of all major separation techniques for proteomic

Daniel C. Liebler masterfully introduces the science of proteomics by spelling out the basics of how one analyzes proteins and proteomes, and just how these approaches are then employed to investigate their roles in living systems. He explains the key concepts of proteomics, how the analytical instrumentation works, what data mining and other software tools do, and how these tools can be integrated to study proteomes. Also discussed are how protein and peptide separation techniques are applied in proteomics, how mass spectrometry is used to identify proteins, and how data analysis software enables protein identification and the mapping of modifications. In addition, there are proteomic approaches for analyzing differential protein expression, characterizing proteomic diversity, and dissecting protein-protein interactions and networks.

The last few years have seen an unprecedented drive toward theapplication of proteomics to resolving challenging biomedical andbiochemical tasks. Separation techniques combined with modern massspectrometry are playing a central role in this drive. This bookdiscusses the increasingly important role of mass spectrometry inproteomic research, and emphasizes recent advances in the existingtechnology and describes the advantages and pitfalls as well. * Provides a scientifically valid method for analyzing theapproximatey 500,000 proteins that are encoded in the humangenome * Explains the hows and whys of using mass spectrometry inproteomic analysis * Brings together the latest approaches combining separationtechniques and mass spectrometry and their application in proteomeanalysis * Comments on future challenges and how they may be addressed * Includes sections on troubleshooting

Food proteomics is one of the most dynamic and fast-developing areas in food science. The goal of this book is to be a reference guide on the principles and the current and future potential applications of proteomics in food science and technology. More specifically, the book will discuss recent developments and the expected trends of the near future in food proteomics. The book will be divided into two parts. The first part (7 chapters) will focus on the basic principles for proteomics, e.g., sample preparation, such as extraction and separation techniques, analytical instrumentation currently in use, and available databases for peptide and protein identification. The second part of the book (26 chapters) will focus on applications in foods. It will deal with quality issues related to post-mortem processes in animal foods and quality traits for all foods in general, as well as the identification of bioactive peptides and proteins, which are very important from the nutritional point of view. Furthermore, consumers are now extremely susceptible to food safety issues, and proteomics can provide reassurance with different safety aspects, such as food authenticity, detection of animal species in the food, and identification of food allergens. All of these issues will be covered in this book. It is also worth noting that both editors are internationally recognized experts in the field of food science, and both have edited numerous food science books and handbooks.

This book covers liquid chromatography, gas chromatography and capillary electrophoresis, the three main separation techniques lately available, applied to key omic sciences, such as genomics, proteomics, metabolomics and foodomics. The fundamentals of each technique are not covered herein. Instead, the recent advances in such techniques are presented focusing on the application to omics analyses and unique aspects in each case. This volume intends to offer wide ranging options available to researchers on omics sciences, and how to integrate them in order to achieve the comprehension of a biological system as a whole. Omic sciences have been of ultimate importance to comprehend the complex biochemical reactions and related events that occurs upon a biological system. The classical central dogma of molecular biology, which states that genetic information flows unidirectionally from DNA to RNA and then to proteins, has been gradually replaced by the systems biology approach. This book presents a multidisciplinary approach that explains the biological system as a whole, where the entire organism is influenced by a variety of internal events as well as by the environment, showing that each level of the biological information flux may influence the previous or the subsequent one.
