X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	6.5	290	1 ul SP-A (10 mg/ml) was mixed with 1 ul reservoir (50 mM sodium cacodylate (pH = 6.5), 1.2-1.6 M lithium sulfate, and 10 mM calcium chloride. After crystals had grown, the drop was diluted about 1/2 with 50 mM sodium cacodylate (pH = 6.5) and 10 mM calcium chloride. Alpha-methylmannose powder was added to the drop and stirred to dissolve. Prior to data collection, the drop was diluted about 1/2 again and more powdered alpha-methylmannose added., VAPOR DIFFUSION, HANGING DROP, temperature 290K
