Prior to the crystallization TF was solubilized in 100 % DMSO in a concentration of 10 mM. TF was mixed with human CK2alpha (construct 1-335; 8-10 mg/ml in 500 mM sodium chloride, 25 mM Tris/HCl pH 8.5) in a ratio of 1:5. 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 the resulting 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. |
