Turning protein crystallisation from an art into a science

Protein crystallisation has gained a new strategic and commercial relevance in the post-genomic era because of its pivotal role in structural genomics. Producing high-quality crystals has always been a bottleneck to structure determination and, with the advent of proteomics, this problem is becoming increasingly acute. The task of producing suitable crystals may be tackled using two approaches. The first relies on empirical techniques that are...
