The transient nature of aggregates during the fibrillation process of α-synuclein is highlighted with in-house SAXS experiments using the BioXolver. Protein aggregation into fibrillar structures is associated with a variety of neurodegenerative disorders, such as Parkinson’s and Alzheimer’s diseases. It is becoming increasingly evident that the toxic species causing the…

SAXS data and 3D envelopes of small and large protein species are obtained through in-line gel filtration. Small-angle X-ray scattering (SAXS) is commonly used to investigate the solution structure of biological macromolecules. Highly accurate results can be obtained with monodisperse solutions devoid of aggregates and impurities. Many biological processes, however,…

Salt concentration and pH impact were studied on lysozyme and BSA systems respectively by investigating various parameters (osmotic second virial coefficient, folding state and 3D shape). Protein-protein interactions are relevant for various biological processes, such as transcription and signal transduction, but also for protein crystallization, stability and shelf-life of pharmaceutical…

3D envelopes were determined from an automated sequence of measurements including 3 different proteins with low volume and dilute solutions. Small-angle X-ray scattering is complementary to other structural biology techniques. It provides reliable information on the shape of proteins in solution and associated parameters including macromolecule interactions and dynamics. Reliability of the…
