Prior to the crystallization the Inhibitor TF85 was solubilized in 100 % DMSO in a concentration of 10 mM. This TF85 stock solution was mixed with human CK2alpha (construct 1-335; Protein concentration 8-10 mg/ml in 500 mM sodium chloride, 25 mM Tris/HCl pH 8.5) in a ratio of 1:10. After a short time of incubation, this mixture was mixed with reservoir solution [32 % (w/v) PEG4000, 0.2 M ammonium acetate, 0.1 M citrate pH 5.6] in a ratio of 5:2. 3.5 microliter of these mixtures were then equilibrated against the reservoir solution. The crystal growth was induced by seeding with 150 nanoliter seeding suspension after an equilibration time of two days. |
