| 1 | VAPOR DIFFUSION, HANGING DROP | 7.5 | 293 | The crystal was grown by hanging drop in conditions optimized from Hampton Index HT G8 (0.2 M Ammonium acetate, 0.1 M HEPES pH 7.5, 25 % w/v polyethylene glycol 3,350). 1 ul 30 mg/mL Y62W Mt PMO9E in 50 mM MOPS, 50 mM MES was mixed with 1 uL with 0.2 M Ammonium acetate, 0.1 M HEPES pH 7.5, and 26% PEG 3,350. The crystal was then cryoprotected for 10 seconds in well solution mixed with cryoprotectants to a final concentration of 8% w/v sucrose, 2% w/v glucose, 8% v/v glycerol, and 8% ethylene glycol |
