Crystallization of little amounts of protein or functionalized protein variants were performed via hanging drop vapor diffusion techniques. Reservoir solution (100 mM Tris, 500 mM MgOAc, pH 8.5) was prepared in a 24- well manual plate set. Drops were prepared on siliconized glass cover slides (Jena Bioscience) by mixing 2 microL reservoir solutions with 1 microL 50 mM Tris, 1 M NaCl, pH 7.5 buffer and 1 microL of respective ferritin variant. Plates were incubated at 298K. After one day first crystals were visible. |
