Compounds for Quantitative Mass Spectrometry

Silantes SILAC and SILAM for quantitative mass spectrometry

The basic principle in quantitative analysis by mass spectrometry is the measurement of a signal representative of the mass of the analyte relative to a known amount of an internal mass standard.

Stable isotope labeled internal standards are compounds in which several atoms in the analyte are replaced by their stable isotopes, such as 2H (D, deuterium), 13C or 15N.

Proteomics and metabolomics using quantitative mass spectrometry aim to identify and quantify proteins and metabolites in a biological samples.

For the accurate quantification of proteins, Silantes offers in-vitro kits and in-vivo diets for SILAC (Stable Isotope Labeling with Amino acids in Cell culture) and SILAM (Stable Isotope Metabolic Labeling in Mammals).

We also produce isotopically labeled nucleosides and nucleotides as internal standards for the accurate quantification of nucleosides and nucleotides by mass spectrometry. The current focus is on providing isotope labeled modified nucleosides
