JRD292 Mass Spectrometry (Protein Identification) Metal Technical Service

First, mass spectrometry (protein identification) group Technical Services Overview

The basic principle of protein mass spectrometry is that after the protein is digested, the peptide mixture is formed, and the peptide segment in the mass spectrometer is ionization to form a charge ion, mass spectrometry analysis The electric field of the unit, the magnetic field will be separated from the peptide ions having a specific mass to the charge ratio (m / z), and the separated ions are collected by the detector, determine the M / Z value of each ion, and therefore, after the mass analyzer can be The M / Z of each peptide segment was analyzed and the primary mass spectrum pattern of the protein was output. The ion selection device automatically selects the strength of the large peptide segment ion for the secondary mass spectrometry. The secondary mass spectrometry peak map selected to select the peptide selection, the primary mass spectrometry peaks and secondary mass spectrum peaks produced by the protein after trypsin digestion. The graph is compared to identify the protein.
