Sample cell arrays and hardware for high-throughput cryoSAXS

Abstract

A system and method of sample cell arrays for performing small-angle X-ray scattering on solutions containing biomolecules and/or other solutes. The sample cell array includes sample cells having a cylindrical cross-section and side walls that are thin compared with their diameter, and preferably made of a compliant material. The cylindrical cells are attached to top and bottom substrates, each with a high transmittance X-ray window, with their axis perpendicular to the respective substrate. The cells are loaded with buffer and buffer+biomolecule solution from an initially open top end. A top substrate (with a sealing cap and the X-ray window) is pushed down onto the cylindrical cells. On cooling to cryogenic temperatures, the thermal contraction of the sample relative to the sample cells does not cause large stresses to develop in the sample once it solidifies and cause sample cracking.
