1 | VAPOR DIFFUSION, HANGING DROP | 7.6 | 291 | Purified TTRwt was dialyzed against 10 mM sodiumphosphate buffer with 100 mM KCl pH 7.6 and concentrated to 5 mg per ml. DNPC was added at 5 x molar excess to the protein. The reservoir contained 1.3 to 1.6 M sodium citrate and 3.5 percent glycerol at pH 5.5. Drop size 3 plus 3 microliter |
