IDMethodpHTemperatureDetails
1VAPOR DIFFUSION, SITTING DROP293The crystals were grown at 20oC using the sitting drop vapor diffusion method. The drop contained 0.2 uL of NbE201 at a concentration of 15 mg/mL-1 and 0.2 uL of PBS buffer pH 7.4, 10 mM Na2HPO4, 1.8 mM KH2PO4, 137 mM NaCl, 2.7 mM KCl, in a cryo-protectant solution of 0.2 M Ca Acetate, 0. 1M Na Cacodylate pH 6.5 with 18% (%v/v) polyethylene glycol 8000 et 33% (%v/v) glycerol before being frozen in liquid nitrogen.
