SILAC is a powerful method to identify and quantify relative differential changes in complex protein samples. This approach entails the in vivo metabolic incorporation of “heavy“ 13C- or 15N-labeled amino acids into proteins followed by mass spectrometry (MS) for the accelerated and comprehensive identification, characterization and quantitation of proteins.


  • Efficient – 100% label incorporation into proteins of living cells

  • Flexible – different isotopes of heavy and/or light amino acids for arginine, lysine, leucine and proline enable the quantitation of peptides derived from MS-grade proteases

  • Multiplex capabilities – several alternative isotopes of arginine and lysine are available that allow the analysis of multiple treatment conditions in each experiment

  • High-quality supplements – heavy amino acids with >99% isotope purity
