Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 5 CRYSTALS WERE GROWN BY VAPOR DIFFUSION ON SITTING DROP BRIDGES. THE WELL MIX OF 20-24% PEG6000 BUFFERED WITH 100 MM NA ACETATE PH 5.0 WAS MIXED 1:1 WITH 3 UL OF I DOMAIN PROTEIN (20-30 MG/ML, 50 MM HEPES PH 7.0, 0.025% NA AZIDE). CRYSTALS WERE STABLIZED IN 100MM MGCL2, 100 MM NA ACETATE 5.0, 26% PEG6000 FOR DATA COLLECTION., vapor diffusion - sitting drop
