Thermo Scientific™ L-Lysine-2HCl, 13C6 for SILAC, 50 mg
On demandThermo Scientific™ L-Lysine-2HCl, 13C6 for SILAC, 50 mg
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. This is a lyophilized preparation of L-Lysine-2HCl (13C6), sufficient for 1 SILAC experiment.
Stable isotope labeling with amino acids in cell culture (SILAC) is a powerful method to identify and quantify relative differential changes in complex protein samples. NeuCode metabolic labeling is similar to SILAC, but differs in that the labeling only utilizes heavy amino acids. The increased multiplexing capability of NeuCode amino acids is possible through the use of mass defects from extra neutrons in the stable isotopes. These small mass differences may be resolved on high resolution mass spectrometers (Thermo Scientific™ Orbitrap™ Elite™, Orbitrap™ Fusion™ Tribrid™, and Orbitrap™ Fusion™ Lumos™ Tribrid™ mass spectrometers). Use of only heavy amino acids eliminates the need for 100% incorporation of amino acids used for SILAC (both heavy and light), and may be especially useful for studies with primary cells.
Features
- 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
