1	VAPOR DIFFUSION, SITTING DROP	5.5	291.15	The protein sample was at 47 g/l in 25 mM Tris/HCl pH 7.6, 10% v/v glycerol and 2 mM dithiothreitol. MCR crystals were obtained aerobically by using the sitting drop method on 96-Well MRC 2-Drop Crystallization Plates in polystyrene (SWISSCI). The crystallization reservoir contained 90 ul of mother liquor; the crystallization drop contained a mixture of 0.6 ul protein sample and 0.6 ul of crystallization solution. The crystallization solution contained 25% w/v polyethylene glycol 3350, 100 mM Bis-Tris pH 5.5 and 200 mM lithium sulfate.
