Crystalization Experiments
Method Vapor Diffusion Hanging Drop
pH 9.3
Temperature 294.0
Details HANGING DROPS (2UL) OF 4.3MG/ML PROTEIN WERE MIXED WITH EQUAL VOLUMES OF RESERVOIR BUFFER CONTAINING 3.7 M SODIUM FORMATE, 2% PEG 3000, 100 MM BICINE (PH 9.3). THE MIXED DROPS WERE STORED AT 21 DEGREES, vapor diffusion - hanging drop, temperature 294K
