Immediately before crystallization, chymotrypsin was added to the sample in a ratio of 1:100 chymotrypsin:protein, and the protein was diluted to 15 mg/mL using MPD, resulting in a final MPD concentration of 25%. Reservoirs were prepared using 750 uL of 100 mM sodium phosphate pH 7.6 and 60% MPD in a Greiner 24-well hanging-drop crystallization plate. On a siliconized glass cover slip (Hampton Research), 1.5 uL of protein were combined with 2.5 uL of reservoir solution and suspended over the well. The plate was incubated at 277 K and crystals were obtained in a few days.

Binding of the ligand has been confirmed biochemically, and ligand disorder outside of the pore center has been observed for other known ligands. More details can be found in the primary citation.
