Cryo: direct: tray 310523 h5: puck PAS1-8. For phasing a crystal from the same tray, well C1 (10% w/v PEG 20 000, 20% v/v PEG MME 550: 30mM of each sodium nitrate, disodium hydrogen phosphate, ammonium sulfate: 100mM MES/imidazole pH 6.5) was incubated for 20sec in a mixture of 10% 5M sodium iodide in ethylene glycol (500mM final NaI concentration) and 90% reservoir solution. Diffraction data were collected in-house.Tray 310523 c1: puck LOF7-9
