X-ray Diffraction and Bio-SAXS core facility is equipped with top-class instruments for diffraction experiments with single crystal samples focused on the determination of the 3-D structure of (macro) molecules down to atomic resolution and for small angle X-ray scattering (SAXS) experiments with isotropically scattering samples focused on determination of the shape and size of macromolecules or nanoparticles.
The range of applicable molecular mass for diffraction methods: from 100 up to 1000000, where the lower value covers molecules significant for nanotechnology, materials science or pharmacology and the upper limit covers biomacromolecules such as nucleic acids, proteins and their complexes.
Range of applicable particle sizes for SAXS: from 2 to 100 nm.
The diffraction of X-rays in single crystal samples is the most important and – if an appropriate sample is available – also the fastest methodology currently available for the determination of the atomic structures of molecules and/or macromolecules and their complexes.
On the other hand, SAXS is a technique capable of determining structural characteristics such as mono dispersity or aggregation, oligomeric state, low resolution three-dimensional shape or even quaternary structure not from a crystal but from a solution of (bio) macromolecules.
The centralized organization of expensive instrumentation for SAXS and single crystal studies and highly trained staff allow the cost-effective use of resources and obtaining of experimental results in rapid responses to the demands of even untrained users.
