1	vapor diffusion - hanging drop - microseeding	5.2		DIFFRACTION-QUALITY CRYSTALS WERE MICROSEEDED IN HANGING DROPS OVER 100 MM SODIUM ACETATE AT PH 5.2, WITH 20% POLY-ETHYLENE GLYCOL 6000 (PEG 6000), 10 MM CALCIUM CHLORIDE AND 0.02% SODIUM AZIDE. STOCK SOLUTIONS OF 24 MG/ML BOVINE BRAIN CALMODULIN (SIGMA LOT 54H9558), 14 MG/ML CAMKII-ALPHA PEPTIDE, AND 30% PEG WERE MIXED INTO HANGING DROPS IN ABOUT A 4-2-1 RATIO., vapor diffusion - hanging drop - microseeding
