We perfrom mass spectrometry based proteomics analysis. Most experiments are done by 'Bottom up' proteomics, where proteins are extracted from the biological samples, subjected to enzymatic digestion followed by liquid chromatography - tandem mass spectrometric analysis. Post-acquisition, the protein identity and quantity is "reconstructed" using cutting edge bioinformatics. Or we can perfrom top down analysis of small proteins using our Fusion Lumos mass spectrometer, equipped with multiple fragmentation technologies. We apply rigorous quality control and criteria for generating the best data from any experiment.

Targeted proteomics

In a ‘targeted’ type experiment we quantify a specific set of proteins using their serrate tryptic peptides. This is conducted using synthetic, stable heavy isotopically labeled peptide standards. The analysis is conducted either on our tandem quadrupole mass spectrometer, in Selective Reaction Monitoring (SRM) mode or on our high resolution quadrupole Orbitrap mass spectrometer, in Parallel Reaction Monitoring mode (PRM). The main advantage of these techniques is the sensitive, specific and reproducible quantification of peptides and proteins.
