Stable isotope labeling by amino acids in cell culture (SILAC) is a relatively new mass spectrometry-based method in proteomics. In a typical SILAC experiment, a cell culture is grown on a medium with isotope labeled amino acids. During the time the cell culture spends on the medium, proteins will be synthesized from the labeled amino acids. The

The BCAA requirement was increased in the new dietary reference intake (DRI) report on the basis of a series of stable isotope studies examining the requirement of leucine and valine individually, but not isoleucine.

Author information: (1)Lipid Metabolism Laboratory, Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, 711 Washington Street, Boston, MA 02111, USA. jmarsh@lifespan.org Here we describe a method, termed SILAC, for stable isotope labeling by amino acids in cell culture, for the in vivo incorporation of specific amino acids into all mammalian proteins. Mammalian cell lines are grown in media lacking a std. essential amino acid but supplemented with a non-radioactive, isotopically labeled form of that amino acid, in this case deuterated leucine (Leu-d3). Two populations of cells are cultivated in cell culture.One of the cell populations is fed with growth medium containing normal amino acids.In contrast, the second population is fed with growth medium containing amino acids labeled with stable (non-radioactive) heavy isotopes.For example, the medium can contain arginine labeled with six carbon-13 atoms (13 C) instead of the normal carbon-12 Although isotope labeled amino acids are expensive, their use has allowed metabolic labeling to be extended to cultured mammalian cells. The Mann laboratory has applied the strategy to mouse fibroblast cells and proposed the term SILAC for stable isotope labeling by amino acids … Stereoselective Synthesis of Triply Isotope-Labeled Ser, Cys, and Ala: Amino Acids for Stereoarray Isotope Labeling Technology.

Protected amino acids. Stable isotopes for structural biology. CortecNet is a Stable Isotopes-driven company. We produce over than 2000 innovative labeled compounds with stable isotopes (13C, 15N, D). Although isotope labeled amino acids are expensive, their use has allowed metabolic labeling to be extended to cultured mammalian cells.
In SILAC, the tryptic amino acids, arginine (R) and lysine (K), contain heavy stable isotopes, so if digesting with trypsin, every peptide is labeled. Stable isotope label amino acids allowed researchers to understand the role of nitrogen fixation in the atmosphere, plants and other organisms, as well as industrial processes. In addition, stable isotope tracers can be used to determine the authenticity and origin of foods such as wine, beef, and olive oil, as well as adulteration of natural products such as honey, juices, jams and syrups.
