Field of application
Separation of peptides according to their physicochemical characteristics.
Coupling to an LTQ-FT ICR mass spectrometer or spotting MALDI target.
Separation principle
The peptides resulting from protein digestion are retained on a column according to its properties (hydrophobicity, ionic force, …).
Applying different solvent gradients allows the progressive elution of these peptides. These gradients are optimized according to the complexity of the sample.
