Click ‘Get a Crystal‘ for details. Staff and Support From February 2000, the laboratory has been used to set up over 24 million crystallization experiments on >16,000 biological macromolecules. Over 1,000 laboratories worldwide have used and benefited from the service.
- At the HTCSC 1,536 different chemical conditions are sampled representing many of the commercially available crystallization screens. Each condition is imaged visually over a period of six weeks. Second Order Non-linear Imaging of Chiral Crystals (SONICC) and UV Two Photon Emitted Fluorescence (UV-TPEF) imaging of crystallization screening also take place to identify biological crystals not picked up visually or those obscured by precipitate.
- Color images, and SONICC and UV-TPEF images are integrated with the analysis software provided as part of the service. Lead crystallization conditions can be identified and the complete set of results used to analyze the samples solubility phase diagram.

In the Literature!
Cyclooxygenase-2 (COX-2) catalyzes the oxygenation of arachidonic acid and endocannabinoid substrates, and has been shown to be inhibited by certain nonsteroidal anti-inflammatory drugs (NSAIDs) in a substrate specific way. Recently, the Malkowski group from University at Buffalo solved X-ray crystal structures of 4 NSAIDs in complex with human COX-2 Top: Visible images of 3 of the initial crystal hits from the HTCSC show brown crystals (the brown color is due to Co(III)-protoporphyrin IX in the protein). The Malkowski group optimized conditions and converted to sitting drop vapor-diffusion. Bottom: Structure of mefenamic acid (pink sticks) bound to human COX-2.
