Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	5.5	290	RigakuReagents, JCSG+ screen, condition a2: 20% PEG 3000, 100mM sodium citrate tribasic / citric acid pH 5.5: MyabA.00786.a.AE1.PS38631 at 26.62 mg/ml: tray 315036 a2, cryo: 20% ethylene glycol, puck rse0-4. For phasing, a crystal from the same well was soaked for 20sec in a solution made of 20% 2.5M sodium iodide in ethylene glycol and 80% reservoir, and then vitrified in liquid nitrogen: tray 315056 a2, puck fdv5-14
