X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7	293	PREB protein was mixed with elastase at 1:1000 (w/w) ratio before setting up crystallization. Crystals were grown at 293 K using the sitting drop method by mixing 0.5 uL protein with 0.5 uL well solution consisting of 1.4M Malonate, pH 7.0. The crystals were cryoprotected by immersion in Paratone.
