Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7.5	293	Protein solution: protein concentration = 5 mg/ml in 50 mM Tris pH 7.5, 100 mM NaCl, 1 mM beta-mercaptoethanol. Chymotrypsin was added in a 1:50 mass-ratio prior to setting up hanging-drop crystallisation trials. Well solution: 10 % w/v PEG 1k and 10 % PEG 10k (Molecular Dimensions Structure Screen 2, condition 46).
