A methodology and an instrument for the temperature-controlled optimization of crystal growth

Acta Crystallogr D Biol Crystallogr. 2007 Mar;63(Pt 3):339-47. doi: 10.1107/S0907444906054230. Epub 2007 Feb 21.


A method and a device for the promotion of crystal growth by keeping the crystallization solution metastable during the growth process are described. This is achieved by controlled temperature variation of the crystallization solution using parameters determined in situ during the growth process. The technique finds application in the growth of large high-quality crystals for neutron crystallography. Thus, it has been applied to grow large crystals of several proteins of interest such as human gamma-crystallin E, PA-IIL lectin from Pseudomonas aeruginosa, yeast inorganic pyrophosphatase, urate oxidase from Aspergillus flavus and human carbonic anhydrase II.
