1 | VAPOR DIFFUSION, HANGING DROP | 296 | Crystals were prepared using hanging drop vapor-diffusion technique at room temperature (~296 K). Protein is at a concentration of 18.5 mg/ml in 50 mM H3BO3, 0.1 M NaCl, pH 9.0 buffer. The well buffer contains 0.1 M glycine, 0.3-0.6 M NaCl, pH 9.0, and 37-39% (v/v) PEG (polyethylene glycol) monomethyl ether 550. 500 uL of well buffer is added to each well and protein is mixed with well buffer at a 1.5 uL:1.5 uL ratio. The crystal growth time was ca. 1-2 weeks |
