Abstract
Stable-isotope labelling by amino acids in cell culture (SILAC) has emerged as a simple and powerful format for quantitative proteomics. What are the current applications for SILAC? And, how will this technology be used in the future? Researchers in many biological areas now routinely characterize proteins by mass spectrometry. Among the many formats for quantitative proteomics, stable-isotope labelling by amino acids in cell culture (SILAC) has emerged as a simple and powerful one. SILAC removes false positives in protein-interaction studies, reveals large-scale kinetics of proteomes and — as a quantitative phosphoproteomics technology — directly uncovers important points in the signalling pathways that control cellular decisions.
