Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	7.5	293	Starting protein solution was 5.5 mg/ml protein in 25 mM sodium carbonate buffer-pH 10.5. The reservoir solution was 500 ul of 2.0 M sodium chloride and 50 mM HEPES-pH 7.5 buffer. Bipyramidal crystals resulted from 2 ul drops, using 0.7 ul protein solution and 1.3 ul well solution.
