| 1 | VAPOR DIFFUSION, SITTING DROP | 293.65 | CRYSTALS WERE GROWN IN SITTING DROPS CONTAINING 200 NL PROTEIN (5.8-6.8 MG/ML) AND 100 NL RESERVOIR SOLUTION (20-18% W/V PEG 3350, 0.10-0.09 M BIS-TRIS PROPANE PH 7.5, 0.2-0.18 M SODIUM CITRATE) EQUILIBRATED AGAINST 95 UL RESERVOIRS AT 20.5 DEGREES CELSIUS. CRYSTALS WERE SOAKED BY DILUTING THE MOTHER-LIQUOR WITH APPROX. 0.5 UL 20% W/V PEG 3350, 0.1 M BIS-TRIS PROPANE PH 8.25 AND 20% V/V GLYCEROL, TRANSFERRING THE CRYSTALS TO A FRESH DROP CONTAINING 20% W/V PEG 3350, 0.1 M BIS-TRIS PROPANE PH 8.25, 20% V/V GLYCEROL, 50 MM MGCL2 AND 10 UM GTP, AND INCUBATING FOR 10 MIN. | |
