  • Apparatus for crystal growth of biomacromolecules
    Patent number: 7819973
    Abstract: A method comprising the steps of continuously changing the concentrations in solution of a biomacromolecule to be crystallized and a precipitant, thereby constructing a crystal phase diagram containing a solubility curve, searching for optimum conditions of crystallization on the basis of the constructed crystal phase diagram, and performing efficient growth of the crystal of the biomacromolecule. Also disclosed is an apparatus for implementing the method.
    Type: Grant
