ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	5.6		CRYSTALS WERE OBTAINED IN SITTING DROPS BY MIXING EQUAL VOLUMES OF THE PROTEIN SOLUTION (10 MG/ML) AND THE PRECIPITATING BUFFER (2M AMMONIUM SULPHATE AND 1% BETA-MERCAPTO ETHANOL, PH 5.6). THE GALACTOSE COMPLEX WAS OBTAINED BY SOAKING C2S CRYSTALS FOR 72H IN THE MOTHER LIQUOR SUPPLEMENTED WITH 10 MM OF GALACTOSE
