The BioSAXS beamline is a highly automated beamline dedicated to the study of proteins, macromolecular complexes, viruses etc., in solution. Samples can be investigated under various conditions (temperature, buffer, pH, kinetics) in a high-throughput manner or a HPLC unit can be used for in-situ (online) purification.
