Two days practical course on the basics of biological Small Angle X-ray Scattering (SAXS) is organised on September 5-6th, 2023 located in Brno, CEITEC (Central European Institute of Technology). Participants will be introduced to the practical aspects of SAXS experiment setup during laboratory practical and excursion to the Core Facility Biomolecular Interaction and Crystallography. One lecture on SAXS basic principles will be open to a broader audience. The computer practicals will be focused on deriving integral parameters from SAXS data, data quality assessment, ab initio modelling and rigid body modelling. Each practical is introduced by a step-by-step tutorial. Participants are encouraged to bring their own SAXS data and didactic cases will be discussed. At the end of the practical course, students will be able to independently acquire the scattering data and understand basic principles and strategies of biological SAXS data analysis.
