What Does AXS Stand For?

AXS stands for Anomalous X Ray Scattering

AXS, or Anomalous X Ray Scattering, is a specialized technique in crystallography and structural biology that leverages the unique scattering properties of X-rays in the presence of anomalous dispersion. This method is particularly useful for determining the three-dimensional structures of complex biological macromolecules and materials by exploiting variations in the scattering amplitudes of atoms under specific conditions. AXS enhances the contrast of heavier atoms within a crystal, enabling researchers to resolve fine details in atomic arrangements and interactions, which is crucial for understanding function and mechanism in various scientific fields.
