1 | VAPOR DIFFUSION, SITTING DROP | 8.5 | 293 | Optimized Ssu72-symplekin crystals were obtained with reservoir solution consisting of 12% PEG3350 (w/v) and 100 mM HEPE pH 8.5. To obtain the tertiary complex structure of Drosophila Ssu72-symplekin-CTD(phos.Ser5), crystals of Ssu72-symplekin were soaked in a mother solution containing 2 mM 19mer CTD(phos.Ser5) peptides overnight at room temperature , VAPOR DIFFUSION, SITTING DROP, temperature 293K |
