1	VAPOR DIFFUSION, HANGING DROP	5.6	277	The protein (NS3 complexed with KK-NS4a(21-39)-KK peptide) was at 12-15 mg/ml in 15 mM MES, pH 6.5 1 M NaCl 20 mM b -mercaptoethanol. Hanging Drops were formed by mixing 4:l protein solution with 4:l {0.75-1.0 M NaCl 0.1M Na/K phosphate 0.1 M Mes, pH 5.8-6.1 20 mM b-mercaptoethanol} The drop was equilibrated the drops over 1 ml {(1.25-1.50 M) NaCl - 0.1M Na/K phosphate 0.1 M Mes, pH 5.6-5.8, 20 mM b-mercaptoethanol} , VAPOR DIFFUSION, HANGING DROP, temperature 277K
