1 | VAPOR DIFFUSION, SITTING DROP | 9.7 | 291 | Concentrated protein in 0.5 mM EDTA, 20 mM Tris-HCL pH 7.5 was mixed with an equal volume of precipitant containing 0.1 M Glycine pH 10.0 and 28% w/v Polyethylene Glycol Monomethyl Ether 2000 and allowed to vapor diffuse against a reservoir of the same precipitant. Before cryoprotection and freezing, the crystal was transferred to a well containing 0.1 M CAPS pH 11.0 and 28% w/v Polyethylene Glycol Monomethyl Ether 2000. The crystal fractured, and a fragment was ued for collection. |
