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.

Tsutomu Terauchi †, Kuniko Kobayashi ‡, Kosuke Okuma † §, Makoto Oba §, Kozaburo Nishiyama §, and ; Masatsune Kainosho ‡ ∥ 2015-12-01 2002-06-01 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.

Each tube of Stable Isotope Labeled Amino Acid mixture contains ~25 nmoles of each labeled amino acid. L-Alanine- 13 C 3, 15 N L-Arginine- 13 C 6, 15 N 4 hydrochloride Stable Isotope Labeled Protected Amino Acids for Peptide Synthesis. Protected amino acids allow for the precise control of the position of labeled amino acids within a peptide of interest allowing researchers to address structural questions. This type of tool can be extremely beneficial in the analysis of membrane proteins, self associating The amino acids are canonical (e.g., arginine, lysine, phenylalanine) and non-canonical (e.g., beta-alanine, citrulline, ornithine) in grades of research and microbiological/pyrogen tested (MPT). They are available as uniformly or specifically labeled with carbon-13, nitrogen-15, deuterium, and oxygen-18 and are often used as metabolic tracers, internal standards, or NMR probes for structure and dynamics.

About 500 amino acids are known though only 20 appear in the genetic code. Strings of amino acids make up proteins, of which there are countless varieties. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. As a supplier of isotope labeled products in
