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 grew, the drop was diluted 1/2 with 50 mM sodium cacodylate (pH =6.5) and 10 mM calcium chloride. Then, mannose powder was added to the drop and mixed to dissolve. A second dilution by 1/2 again and addition of more mannose powder preceded data collection., VAPOR DIFFUSION, HANGING DROP, temperature 290K
