| 1 | 4.5 | 293 | CRYSTALS OF NITRATE-LYSOZYME WERE GROWN UNDER A MICRO GRAVITY ENVIRONMENT DURING THE USML-2 MISSION LAUNCHED ON OCTOBER 1995 (SHUTTLE COLUMBIA). THE CRYSTALLIZATION SETUP WAS THE APCF DEVELOPPED BY EUROPEAN SPACE AGENCY. PROTEIN CONCENTRATION 10 MG/ML IN 50 MM SODIUM ACETATE BUFFER AT PH 4.5. GRADIENT CONCENTRATION APPLIED FROM 0 TO FINAL 290 MM AT 293K | |
