| 1 | VAPOR DIFFUSION, SITTING DROP | 7.5 | 295 | 12-15% PEG 4000 OR PEG 3000, 0.1M MGCL2, 0.015M BETA MERCAPTOETHANOL, 0.1M TRIS-DCL, PD 7.9, 0.4M NASCN. All dissolved in D2O. Crystal grown in a 15 + 15 microlitre sitting drops that was first equilibrated for 1 week. A crystal grown at 20-28% PEG was introduced. The drop was fed with fresh protein by adding 3-4 micro litres of protein with 10 mM lactose every 3-4 days for 3 months. For details see Manzoni et al. (2016). |
