1VAPOR DIFFUSION, HANGING DROP298FOR CRYSTALLIZATION, THE PURIFIED PROTEIN WAS CONCENTRATED TO 19.88 MG/ML. APO - NDM - 1 CRYSTALS WERE GROWN AT 25 C FOR 3 WEEKS USING THE HANGING - DROP VAPOUR DIFFUSION METHOD BY MIXING 0.7UL OF PROTEIN SOLUTION WITH 1UL OF RESERVOIR BUFFER (24 % PEG 1500 AND 0.05 M TBG (SODIUM TARTRATE/BIS - TRIS/GLYCYLGLYCINE) PH 4) AND 0.3UL OF 1/10 DILUTION OF NDM - 1 CRYSTAL SEEDS STOCK.
