Overview
Stable Isotope Labeling by Amino Acids in Cell Culture (SILAC) is a powerful nutritional and metabolic labelling technique used to study proteins in cells. It involves replacing the natural amino acids in a cell culture with synthesized forms of the same amino acids that are isotopically labelled. This leads to the production of proteins that contain the isotopic labels, which can be used to measure and quantify the proteins over time. SILAC is a highly sensitive and accurate method that can be used to study changes in protein abundance caused by external stimuli or mutations, enabling the comprehensive analysis of protein expression. Additionally, SILAC can be used to study post-translational modifications such as phosphorylation and glycosylation, and to analyze protein-protein interactions. Overall, SILAC technique allows researchers to gain insights into the underlying molecular mechanisms of diseases, making it a powerful tool for biomedical research.
