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. The SILAC is a metabolic labeling strategy that uses stable isotope-labeled amino acids in growth medium to encode cellular pro-teomes for quantitative analysis3–6.

These materials represent the highest isotopically enriched amino acids that are commercially available and offered in their research grade and/or microbiological/pyrogen tested (MPT) form. Stable Isotope Labeled peptides with non-radioactive isotopes are used for conventional detection in research.

Edward Takach et. al Journal of chromatography. 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. In order to incorporate the stable isotope label into these proteins, researchers use labeled amino acids in a variety of methods that include peptide synthesis, cell-free protein synthesis, and microbial growth by media.

During the time the cell culture spends on the medium, proteins will be synthesized from the labeled amino acids. The SILAC is a metabolic labeling strategy that uses stable isotope-labeled amino acids in growth medium to encode cellular pro-teomes for quantitative analysis3–6. Isotope-edited IR of proteins has generated considerable interest. Double labeling with 13 C and 18 O with high levels of isotopic enrichment is required for residue-specific resolution.

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.
