Crystallization remains the bottleneck in the crystallographic process leading from a gene to a three‐dimensional model of the encoded protein or RNA. Automation of the individual steps of a crystallization experiment, from the preparation of crystallization cocktails for initial or optimization screens to the imaging of the experiments, has been the response to address this issue. Today, large high‐throughput crystallization facilities, many of them open to the general user community, are capable of setting up thousands of crystallization trials per day. It is thus possible to test multiple constructs of each target for their ability to form crystals on a production‐line basis. This has improved success rates and made crystallization much more convenient. High‐throughput crystallization, however, cannot relieve users of the task of producing samples of high quality. Moreover, the time gained from eliminating manual preparations must now be invested in the careful evaluation of the increased number of experiments. The latter requires a sophisticated data and laboratory information‐management system. A review of the current state of automation at the individual steps of crystallization with specific attention to the automation of optimization is given.
