After several weeks, crystals appeared in 2 M LiSO4, 100 mM Sodium acetate pH 5.5, 100 mM MgSO4 and 5% v/v PEG 400. jHmdII crystal was cryoprotected in its mother liquor supplemented with 30% ethylene glycol before freezing in liquid nitrogen. Temp details: The temperature fluctuation was +/- 1 degree
