ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	8.5	289	TNFa (VCID10616, B114005) at 10 mg/ml (in 10 mM HEPES, pH = 7.5, 150 mM NaCl) was mixed with an equal volume of protein solution and a solution containing 24% (w/v) PEG-4000, 0.24 M MgCl2, 0.05% DDM, and 0.1 M HEPES/NaOH, pH=8.5. Crystals were produced by sitting drop vapor diffusion at 16 degrees Celsius. Crystals were then soaked with the same solution supplemented with 10% MTSL for one week and harvested with paraffin oil.
