| 1 | VAPOR DIFFUSION, HANGING DROP | 4.2 | 298 | HEWL crystals were grown at 293 K using the hanging drop vapour diffusion method. The reservoir (600 UL) contained 20 mM sodium acetate buffer at pH 4.2 and 1.0 M NaCl; the drop (0.5+0.5 UL) contained hen egg white lysozyme (10 mg mL-1) in the same acetate buffer (5mM) and reservoir solution. Crystals grow in 1 day. After 5 days, HEWL crystals were soaked in a DMSO solution of cis-PtI2(NH3)2. Final concentration of the metal complex in solution was >10 times higher than HEWL, VAPOR DIFFUSION, HANGING DROP, temperature 298K |
