| 1 | VAPOR DIFFUSION, SITTING DROP | 5.66 | 281 | Crystal were obtained from a 400 nL drop formed from 200 nL of protein solution (11.2 mg/mL, in 10 mM Tris-HCl, pH 8.0) and 200 nL of precipitant (polyethylene glycol 3350 15.7% w/v, malic acid 100 mM, pH 5.66). The drop was incubated at 281K. The reservoir (80 micro-L) contained polyethylene glycol 3350 (15.7% w/v) and malic acid (100 mM, pH 5.66)., VAPOR DIFFUSION, SITTING DROP |
