Crystalization Experiments
Method Vapor Diffusion Hanging Drop
pH 6.5
Details PROTEIN WAS CRYSTALLIZED IN THE HANGING DROP VAPOR DIFFUSION METHOD. THE RESERVOIR SOLUTION CONTAINED 18% PEG8000, IN 25MM MES BUFFER, PH6.5. THE HANGING DROP WAS A 1:1 MIXTURE OF THE RESERVOIR SOLUTION AND THE PROTEIN SOLUTION WHICH CONTAINED 10MG/ML PROTEIN IN 25MM MES BUFFER, PH6.5., pH 6.50, VAPOR DIFFUSION, HANGING DROP
