1	VAPOR DIFFUSION, SITTING DROP	4.5	290	18.9 mg/mL NegoA.19180.a.B1.PS38025 + Microlytics MCSG1 screen A5: 1260 mM ammonium sulfate, 200 mM sodium chloride, 100 mM sodium acetate / acetic acid, pH 4.5, tray: 284201 A5, native data set, cryoprotectant: 25% ethylene glycol, puck gsg8-9. For phasing, a crystal from the same condition was incubated for 15 seconds each in 12.5% ethylene glycol, 625 mM potassium iodide in reservoir and 25% ethylene glycol, 1250 mM potassium iodide in reservoir, puck viy9-1. Anomalous data was collected in-house.
