We make the protein identification present in complex or purified samples, which are in solutions or electrophoresis SDS-PAGEgels. After the appropriate sample preparation, the proteins are digested with trypsin and the resulting peptides are analyzed by advanced mass spectrometry. The MS/MS data obtained are compared with data banks for the identification of proteins.

We make the analysis of protein differential expression by absolute quantification (stable isotypes) or relative (spectral counts) of complex or purified proteins.
