1 | VAPOR DIFFUSION, SITTING DROP | 7.5 | 281 | The drop consists of 1 ul of enzyme solution containing ~5 mg/ml HcgC, 2 mM pyridinol (dissolved in 100% DMSO) and 2 mM SAH mixed with 1 ul of the reservoir solution : 100 mM HEPES/NaOH pH 7.5, 0.1 M NaCl, and 30% 2-Methyl-2,4-pentanediol. After only 4 days the crystals were immediately fished and frozen in liquid nitrogen for synchrotron radiation. |
