Abstract

A system for crystallizing a protein and other biomolecules comprises a flow channel for conveying a solution containing the biomolecule to be crystallized and one or more substations related to the crystallization process formed along the flow channel. The system operates by flowing a biomolecule solution through a the flow channel, then performing dialysis on a micro-scale to set crystallization conditions. After dialysis, the concentration of the biomolecule solution is changed by removing water or solvent from the biomolecule solution to promote formation of crystals in a segment of the flow channel. Formed crystals may be observed and harvested from the flow channel.
