Overview The HTP Crystallization Laboratory at HWI
Microbatch Under Oil Chayen, N.E., Stewart, P.D.S., Blow, D.M., Journal of Crystal Growth, 122 (1992) 176-180.
The Experiment Plate Each plate contains one sample x 1536 unique chemical cocktails
Setting Up the Plates Source/Destination Plate Methods Reformat Plates from Low to High Density Modified Robbins Scientific Hydra 96 and 384 are used to deliver the solutions
Animated Views 1536 different Bovine liver catalase crystallization experiments were setup. Every experiment was recorded 203 times at 30 minute intervals. Still images were used to produce time- lapse recordings of the experiments. Determine preliminary outcomes that could lead to crystallization.

Conclusions HTP crystallization can have dual roles: 1) A method to produce crystals 2) A tool for knowledge discovery Setting up a lot of crystallization experiments is not a cure-all (GIGO). Method variation can produce different results. Image quality is critical for success. Verification of the outcomes’ composition is an important focus for development.
