1 | VAPOR DIFFUSION, HANGING DROP | 8 | 298 | 1uL of scLXRbeta-LBD/scRXRbeta-LBD @ 10 mg protein/ml in 20 mM Tris-HCl pH 8.0, 150 mM NaCl, 5 mM DTT containing 1mM ligand and less than 2%(v/v) DMSO was mixed with 1uL of reservoir solution (0.2M LiCl, 16-20%(w/v) PEG3350, 7-10%(v/v) ethylene glycol, 0.01M Strontium chloride) on a circular, silanized glass cover slide and inverted and sealed with silicon grease over a well of 200uL of reservoir solution. Crystallization plates were incubated at 23 deg C for 2-5 days before rods would appear measuring 50 to 100um long. |
