Description

Thermo Scientific™ Heavy and Light Amino Acids are used to specifically analyze protein expression by mass spectrometry using stable isotope labeling with amino acids in cell culture (SILAC) quantification kits.

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.

Highlights:

• 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
