Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7.5	277.15	Protein and peptide were mixed at a 1:2 molar stoichiometry with a final protein concentration of 12 mg/mL in crystallization buffer. This was used during hanging-drop crystallization in a 1:1 ratio with 0.1 M HEPES pH 7.5, 0.2 M CaCl2, 5% glycerol, 2 mM BME and 28% PEG400. Crystals were grown within 10 days at 4 C and fragment soaking was performed on crystals of 10 days and older by adding 0.2 uL of a 100 mM stock solution in dimethyl sulfoxide to 2 uL drops containing multiple crystals.
