| 1 | VAPOR DIFFUSION, SITTING DROP | 7.5 | 293 | 750 nL purified protein at 7.5 mg/mL in 50 mM HEPES, pH 7.0, 150 mM NaCl, 2 mM DTT was mixed with 250 nL of seed stock and 1000 nL of a precipitant consisting of 18-23 % (w/v) PEG-3350, 0.2 M ammonium sulphate, 0.1 M PCTP pH 7.5. Seed stock was prepared using a Seed BeadTM (Hampton Research) from a co-crystal of GS-PARG(448-976 [K617A, Q618A, K619A, E688A, K689A, K690A]) with ADP-ribose, with co-crystallisation mother liquor (19 % (w/v) PEG-3350, 0.2 M ammonium sulphate, 0.1 M PCTP pH 7.5) as the stabilising solution. The final volume of the seed stock was 100 microL. |
