DXMS-guided Design of Well Crystallizing Proteins

The exchange-quenched solution is then injected onto the protein processing system which includes injection loops, protease column(s), a trap column, an analytical column, electronically controlled valves, and isocratic and gradient pumps. 

The injector, columns and valves reside in a low temperature chamber to minimize the loss of deuterium by back exchange (Fig. 12.2). The quenched protein solution is pumped in series through a column containing an immobilized protease and a trap column to capture the peptide fragments. The gradient pump is activated following digestion and the peptides captured on the trap column are eluted and separated over an analytical reverse-phase HPLC column directly into the mass spectrometer.
