This book is designed to help scientists without a strong background in analytical chemistry to understand basic analytical principles so they can apply them to proteomics profiling. It will also help researchers with an analytical chemistry background to break into the proteomics field. The title focuses on practical applications for proteomic research so readers are guided to design better experiments and to more easily interpret the resulting data. Bridges the gap between overly specialized courses and books in mass spectrometry, proteomics and analytical chemistryCovers the analytical consequences of protein and peptide modifications that may have a profound effect on how and what researchers actually measure; other books do not discuss such issuesIncludes real life examples illustrating the importance of problems in quantitation and validation of biomarkers from the perspective of analytical chemistry with additional references to other sources Helps in designing and executing proteomic experiments with sound analytics.
