This detailed volume explores the most recent methodologies and applications of stable isotope labeling by amino acids in cell culture (SILAC). With the development of new technologies in the field of mass spectrometry and bioinformatics, SILAC-based methods have become the first tool of choice in quantitative proteomics either on its own or in combination with other more recently developed approaches, which is elucidated in the chapters of this book. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, SILAC: Methods and Protocols serves as an ideal guide for researchers working in the area of functional proteomics and other aspects of protein science.
