1	VAPOR DIFFUSION, SITTING DROP	7	294	Reservoir solution: 100 mM Tris HCl pH 7.0; 0.4 M NaH2PO4; 1.466 K2HPO; 0.2 M NaCl 10 mg/mL Protein solution: CPSF3 protein in; 20 mM Hepes pH 7.7; 150 mM NaCl; 5 % glycerol; 1 mM DTT; 0.5 mM NVP-LTM531 Co-crystallization Protocol: 50 nL of protein mixed with 50 nL of reservoir solution. Crystals grew within 1 day with tetragonal bipyramidal habitus and reached a maximum size of 50 micrometers after 3 days. Cryo-protection Protocol: supplemented reservoir solution with 10 and 20% glycerol, respectively, and subsequently added both solution within 5 min. Crystals incubate for another 5 min before harvesting.
