Key Points
- To assess the viability of small angle X-ray scattering combined with multi-wire area detectors for tracking large conformational changes in myosin in solution.
- Applied small angle X-ray scattering (SAXS) using standard laboratory X-ray sources to examine biological macromolecules in solution.
- Utilized high-efficiency, low-noise multi-wire area detectors in place of conventional photographic film to record scattering patterns.
- Multi-wire area detectors reduced pattern acquisition time to 1–2 hours for a typical protein using laboratory sources, circumventing photographic film limitations.
- The system successfully characterized a large structural conformational change in myosin.
