1	VAPOR DIFFUSION, HANGING DROP		277.15	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 BFRF1::BFLF2 were obtained at 4 degree C with 0.2 M sodium malonate, pH 4.5, 20% PEG 3350 as a reservoir solution.
