| 1 | VAPOR DIFFUSION, SITTING DROP | 8.5 | 290 | Microlytic MCSG-1 screen, condition g7: 25% (w/V) PEG 3350, 100mM Tris base / HCl pH 8.5: StmaA.00952.a.B1.PW38746 (labelled as StmaA.01067.a.B1.PW38746) at 9mg/ml: tray 314074g7: cryo: 15% EG: puck qvy9-5. For phasing, a crystal from the same condition was incubated for 20sec in a mix of 90% reservoir and 10% 2.5M NaI in EG, followed by a soak for 20sec in a mix of 80% reservoir and 20% NaI in EG. cryo: 20% EG + 500mM NaI: puck ynn3-13 |
