Then, this inhibitor stock solution was mixed in a Ratio of 1:10 with human CK2alpha (construct 1-335; solved with a Protein concentration of 8-10 mg/ml in 500 mM sodium chloride, 25 mM Tris/HCl pH 8.5). After a short time of incubation this mixture were mixed with reservoir solution [32 % (w/v) PEG4000, 0.2 M ammonium acetate, 0.1 M citrate pH 5.6] in a ratio of 2.5:1. 3.5 microliter of this final mixture was then equilibrated against the reservoir solution. The crystal growth was induced by seeding with 150 nanoliter seed suspension after an equilibration time of two days. Resolution 1.64 Å R-free 0.184
