Microfluidic Cell for Studying the Precrystallization Stage Structure of Protein Solutions by Small-Angle X-Ray Scattering

A microfluidic cell has been developed for studying the structure of protein solutions using small-angle X-ray scattering. The use of prefabricated elements, which provide a small sample volume, allows one to adjust the microfluidic cell parameters to specific problems. Tests of lysozyme solutions were performed on a laboratory diffractometer AMUR-K (Institute of Crystallography, Russian Academy of Sciences), BM29 beamline (ESRF, Grenoble), and...
