X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	4.5	293	Drops comprised 2microliters protein solution mixed with reservoir buffer consisting of 100mM sodium acetate pH 4.5, 14% PEG400 and 50mM calcium acetate. After 2 days they were streak seeded with crystals obtained from rolipram complex seed stock. Crystals, up to 100 microns in largest dimension, grew from precipitate after 1-2 weeks. Crystals were transferred to a cryoprotectant solution (100mM sodium acetate pH 4.5, 14% PEG400, 50mM calcium acetate and 20% glycerol) then flash-frozen prior to X-ray data collection.
