title: Native mass spectrometry as a tool in structural biology.
abstract: Native mass spectrometry (native MS) gives information about the composition, topological arrangements, dynamics, and structural properties of protein complexes. The mass range is principally unlimited and highly dynamic, allowing the detection of small subunits and large complexes within the same measurement. The amount of protein needed for an analysis is, compared to most other structural biology methods, very low. This unit provides an introduction to native MS. It starts with an explanation of the basic method and details on how to measure intact proteins and protein complexes, and continues with the study of dynamics and complex stability in the gas phase. The final section discusses the most recent extension to the native MS field, ion mobility, which allows the direct assessment of the structural properties of the complexes of interest.
