X-RAY DIFFRACTION

Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	?	295	SPOP MATH was at 24 mg/ml and 1:5 protein:53BP1 peptide molar ratio. Crystals were grown by the hanging drop method, mixing 2 ul of the protein sample in 20 mM Tris-HCl, pH 7.6, 150 mM NaCl, 5 mM DTT and 2 ul of the reservoir solution for the drop. The reservoir solution was 0.5 ml. Reservoir solution: 0.1 M sodium citrate tribasic dihydrate, pH 5.6, 0.2 M (NH4)2SO4, 1 M Li2SO4
