Crystallization

Crystalization Experiments
pH 4.6
Details CRYSTALS WERE GROWN BY MIXING EQUAL VOLUMES OF A 25 MG/ML VANCOMYCIN SOLUTION AND 2.2 M NACL, 0.1 M SODIUM ACETATE, PH 4.6 (RESERVOIR BUFFER) AND THEN SUSPENDING THIS DROP OVER THE RESERVOIR. CRYSTALS WERE GROWN AT 293 K., VAPOR DIFFUSION - HANGING DROP
