Quantitative Proteomics

Relative quantification of proteins is the core business of biomarker discovery in proteomics. The label-free technics used in the Facility allows identifying from one hundred to more than four thousands of proteins in complex samples and to relatively compare their abundances between the different samples.

Absolute quantification is applied to a defined set of proteins to achieve a very accurate quantitation of those proteins usually by using stable isotope labeled standards.
