Native MS is a non-denaturing technique which allows to preserve noncovalent interactions and quaternary protein structure in the gas phase. Unlike conventional denaturing MS, which often includes organic solvents and low pH, native MS uses volatile, aqueous buffers at near physiological pH and gentler temperatures and voltages. This enables the study of protein-protein interactions, protein-ligand interactions, subunit architecture, and complex stoichiometry.

The equipment is characterized by a Cell Imaging tool combined with a Multi-Mode Reader and an incubator-like system for real-time live cell and longer-term kinetic studies. The instrument should work by multiple advanced combined technologies, including fluorescence and high contrast brightfield imaging, monochromator-based ultraviolet and visible (UV-VIS) absorbance, high performance filter-based fluorescence and luminescence.
