1 | VAPOR DIFFUSION, HANGING DROP | 277 | The protein was dissolved in a buffer consisting of 50 mM TrisHCl, 150 mM NaCl, pH 7.5 and concentrated to values between 10-15 mg/ml. Diffraction quality crystals of pUL50::pUL53 were obtained at 4 degree C with 20% PEG 4000, 10% propanol, 100 mM HEPES, pH 7.5 as a reservoir solution. |
