X-RAY DIFFRACTION	?	288	1 ul BchL protein in 100 mM HEPES pH 7.5, 150 mM NaCl, 10% (v/v) glycerol was mixed with 2 ul well solution containing 0.6 M sodium chloride, 0.1 M MES:NaOH pH 6.5, 20% (w/v) PEG 4000. Prior to freezing, the well solution was mixed in an equal volume of cryoprotectant solution with a final concentration of 9% (w/v) sucrose, 2% (w/v) glucose, 8% (v/v) glycerol, and 8% (v/v) ethylene glycol. Crystals were soaked for a few seconds in the cryoprotectant before being frozen in liquid nitrogen
