Curated repository for small angle scattering data and models

SASBDB currently contains:


experimental data sets


586 experimental data sets on hold
647 models on hold

Small angle scattering (SAS) of X-ray and neutrons provides structural information on biological macromolecules in solution at a resolution of 1-2 nm.
SASBDB is a fully searchable curated repository of freely accessible and downloadable experimental data, which are deposited together with the relevant experimental conditions, sample details, derived models and their fits to the data.
