1 | VAPOR DIFFUSION, SITTING DROP | 290 | For native data collection: Anatrace Morpheus screen G7: 20mM of each Sodium formate, Ammonium acetate, Sodium citrate tribasic dihydrate, Sodium potassium tartrate tetrahydrate, Sodium oxamate: 100mM Na-HEPES / MOPS acid pH 7.5: 40% (V/V) Glycerol, 20% (w/V) PEG 4000: ButhA.17888.a.AE1 (labled as CrpaA.01056.a.AE1.PW38685) at 30.5mg/ml: 311984 g7: cryo: direct: puck ocs5-5. For phasing, a crystal from the same tray, condition H9 (20mM of each L-Na-Glutamate, Alanine (racemic), Glycine, Lysine HCl (racemic), Serine (racemic): 100mM Tris base / Bicine pH 8.5: 40% (v/v) PEG 500 MME, 20% (w/V) PEG 20000) was incubated for 30sec in a mix of 90% reservoir and 10% 5M NaI in ethylene glycol and vitrified without further cryoprotection. 360deg of data were collected in-house at Cu-Ka radiation.Tray: 311984 h9, puck ocs5-14. | |
