| 1 | VAPOR DIFFUSION, SITTING DROP | 6.5 | 291 | protein solution: BLVRB at 18 mg/mL in 50 mM Bis-Tris, pH 6.5, 50 mM NaCl, 1 mM DTT, 1 mM NADP+ well solution: 0.1 M MES monohydrate pH 6.5, 10-12% (w/v) PEG 20,000, and 25% (v/v) MPD. Crystallization droplets comprised 0.5 uL protein solution was mixed with 0.5 uL of well solution. BLVRB/NADP+ crystals were soaked for approximately 1 hour in a drop containing 2.5-5 mM BCT2104 (dissolved in 100% DMSO) and vitrified with 30% (v/v) glycerol as cryoprotectant. |
