[SA_scat] X+: New X-Ray Scattering Analysis Software

Dear Colleagues,

Please see below for details of a new software package developed in our Institute.

Regards,
Uri Raviv

Our software program, X+, analyses X-ray scattering from macromolecules in solution. Thoroughly analyses both structure and form factors to model the entire scattering signal, allowing extraction of relevant physical parameters including electron-density distribution, correlation distances, domain sizes, elastic constants and parameters describing intermolecular interactions.

Key Features


  *   X+ provides a means to easily study and thoroughly analyze many important biological self-assembled structures and soft-matter supramolecular structures.
  *   Can be used to investigate non-crystalline self-assembled structures with features spanning length scales in the range 0.1– 200 nm.
  *   Enables the analysis of solution X-ray scattering from self-assembled systems, including liquid crystals, self-assembled polymers, various supramolecular complexes and particularly biomolecular assemblies.

The Opportunity

System may be used for analyzing all types of large molecular structures in solution, such as:

  *   Viruses
  *   Microtubules
  *   Nanostructures
  *   Membranes
  *   Liquid crystals
  *   Polymer assemblies
