Crystallization Conditions
crystal ID | method | pH | temperature | details |
1 | VAPOR DIFFUSION, SITTING DROP | 6.5 | 298 | Vapor diffusion in Cryschem sitting drop plates at room temperature. Reservoirs were Dulbeccos Phosphate buffered saline at pH 6.5. Drops were equal amounts of the reservoir and a 40 mg/ml solution of the protein dissolved in water with a trace of ammonium hydroxide. Crystallization time was 24 to 48 hours. |
