1 | VAPOR DIFFUSION | 5.2 | CRYSTALS OF THE ENZYME-INHIBITOR COMPLEX WERE GROWN BY VAPOUR DIFFUSION METHOD AGAINST PRECIPITANT SOLUTION CONTAINING OF 38% MPD AND 0,05 M SODIUM ACETATE BUFFER PH 5.2. DROPLETS OF 10-15 MKL CONTAINING 25-30 MG/ML PROTEIN SOLUTION IN THE SAME BUFFER WERE MIXED BEFORE CRYSTALLISATION WITH EQUAL VOLUME OF PRECIPITANT SOLUTION. |
