1VAPOR DIFFUSION, SITTING DROP8.62930.1 M Tris (base) bicine pH 8.2 - 8.8, 17 - 21% v/v PEG 500 MME, 8 - 10% w/v PEG 20000. Before setting up the drops 13 mg ml-1 Vc1313-LBD was mixed with 10 mM D-lysine from a 200 mM stock. The protein-ligand mixture was then mixed with reservoir solution in a 3:1 ratio. Before flash freezing the crystal in liquid nitrogen, the PEG concentrations were raised to 23% v/v PEG 500*MME, 12% w/v PEG 20000.
