1 | VAPOR DIFFUSION, SITTING DROP | 285 | A solution containing 18.9 mg/mL His6-tagged SuiB in in storage buffer [100 mM HEPES, pH 7.5, 300 mM KCl, 5 mM DTT, 10% (v/v) glycerol] was mixed 1:1 with precipitant solution. Small clusters of crystals were formed within 24 hrs. A seed stock was then produced by combining a single sitting well with 10 uL of reservoir solution and 10 uL of enzyme at 8 mg/mL, followed by brief vortexing. Following seeding, a resulting crystal was incubated in precipitant solution containing ~6 mM SAM for 30 min prior to transfer to cryosolution.The precipitant solution was 100 mM MES, pH 6.0, 15% (w/v) PEG 3350. |
