Proteomics by 2D Gels

Two-dimensional Gel Electrophoresis

Cut out Spots and Identify Proteins by Tandom Mass Spectroscopy

Each peptide could be broken into many possible smaller fragments

Each ion will have its own mass to charge ratio

The real spectrum is compared to all possible spectra for a given species and the peptide sequence is identified
