By maintaining intact multi-protein complexes in the gas-phase, native mass spectrometry provides their molecular weight with very good accuracy compared to other methods (typically native PAGE or SEC-MALS) (Marcoux and Robinson, Structure 21:1541-1550, 2013). Besides, heterogeneous samples, in terms of
