    Method vapor diffusion - hanging drop
    pH 7
    Temperature 296.0
    Details THE FULL-LENGTH VHR (RESIDUES 2 - 185) WAS CRYSTALLIZED AT A CONCENTRATION OF 5-6 MG/ML WITH 14% POLYETHYLENE GLYCOL 4000, 22.5 MM LITHIUM SULFATE, 50 MM HEPES PH 7.0, AND 0.05% BETA-MERCAPTOETHANOL IN A HANGING DROP OF 20 MICROLITERS. THE DROP WAS EQUILIBRATED AGAINST 1 ML OF TWICE THE CONCENTRATION OF PRECIPITANT SOLUTION AT 23 DEGREE CELSIUS., vapor diffusion - hanging drop, temperature 296K
