Pepsi-SAXS is a new, highly efficient method for computation of X-ray scattering profiles, which are needed for solution-state protein molecule analysis. The method was created by scientists from the Université Grenoble Alpes and MIPT, led by Sergei Grudinin. The team tested their method, and the results were published by the International Union of Crystallography in its journal Acta Crystallographica Section D: Structural Biology.
