Crystal grow | Temperature: 295 K / Method: vapor diffusion, sitting drop / pH: 7.5 Details: Protein solution:( 12/mg/mL in 100mM HEPES pH 7.5, 150mM NaCl, 10mM MgCl2 2mM DTT) Well solution: (20% PEG3,350 and 0.2M potassium citrate tribasic monohydrate). 4uL of S-adenosyl methionine ...Details: Protein solution:( 12/mg/mL in 100mM HEPES pH 7.5, 150mM NaCl, 10mM MgCl2 2mM DTT) Well solution: (20% PEG3,350 and 0.2M potassium citrate tribasic monohydrate). 4uL of S-adenosyl methionine in water were added to 100uL of protein and allowed to incubate on ice for 1 hour before protein was mixed with well at 1:1 ratio.Seeding used to improve crystals. Compound stock solutions (either 100mM or 1M stocks) were added up to a final drop concentration of 4.8% DMSO. Crystals were soaked for 4-6 hours. 20% glycerol in well solution was used as cryoprotectant for a quick dip of crystal in liquid N2. |
