The hanging drop vapor diffusion method was used to form the bipyramidal crystals of the MDR 769 protease. Using a grid screen consisting of sodium chloride (0.7 to 1.4 M) and MES-HEPES buffer (pH 5.5 to 8.1), the HIV-1 protease substrate complex crystals formed overnight at 22 C. Routinely, 0.2 mm crystals, in the longest dimension, were obtained after 14 days of incubation. In each well, there were two droplets, containing 1 lL of protease substrate mixture, 1 lL of reservoir solution and 2 lL of protease substrate mixture, 1 lL of reservoir solution, respectively, 07 mL of well solution., VAPOR DIFFUSION, HANGING DROP, temperature 298K |
