AFTER EXTENSIVE INTIAL SOAKING, THE SALT CONCENTRATION WAS SUCCESSIVELY LOWERED OVER A PERIOD OF 8 MONTHS WHILE IN PARALLEL THE CONCENTRATIONS OF DMSO AND PEG 6000 WERE INCREASED. THIS WAS DONE BY GRADUALLY REPLACING THE RESERVOIR AND THE DROPLET SOLUTION UNTIL ANY NACL WAS REMOVED, THE LICL CONCENTRATION WAS REDUCED TO 50 MM, THE PEG 6000 CONCENTRATION WAS INCREASED TO SATURATION AND A DMSO CONTENT OF 30% WAS REACHED.

THE GTP-ANALOGUE GMPPNP WAS COMBINED WITH THESE CRYSTALS BY SOAKING. A 20 MM GMPPNP SOLUTION IN 60 MM MGCL2 WAS PREPARED. FOR SOAKING, 3 MICROLITER OF THE CRYSTAL MOTHER LIQUOR WAS REMOVED AND REPLACED BY 3 MICROLITER OF 20 MM GMPPNP, 60 MM MGCL2. ALL STEPS WERE PERFORMED AT A TEMPERATURE OF 293 K.
