title: Stable isotope labeling with amino acids in cell culture (SILAC) for studying dynamics of protein abundance and posttranslational modifications.
abstract: Stable isotope labeling with amino acids in cell culture (SILAC) is a simple and straightforward approach for in vivo incorporation of a tag into proteins for relative quantitation by mass spectrometry. SILAC is a simple, yet powerful, method for investigating the dynamics of protein abundance and posttranslational modifications. Here, we provide detailed instructions for using this method to study protein complexes, protein-protein interactions, and the dynamics of protein abundance and posttranslational modifications. We expect that SILAC will become a routine technique because of its applicability to most areas of cell biology. We have also developed a Web site (http://www.silac.org) to provide researchers with updated information about this method and related resources.
