Crystallization

Crystalization Experiments
Method Vapor Diffusion Sitting Drop
pH 5.3
Temperature 293.0
Details CRYSTALS GROWN BY VAPOR DIFFUSION IN A SITTING DROP USING EQUAL VOLUMES OF PROTEIN AND RESERVOIR. CRYSTALLIZATION OCCURED OVER A PERIOD OF SEVERAL DAYS AT 20 DEGREE CELSIUS. PROTEIN (15 MG/ML) WAS IN 25MM TRIS-HCL, PH=8.0, 100MM NACL, 5MM MGCL2. RESERVOIR CONTAINED: 51% SATURATED AMMONIUM SULFATE, 100 MM SODIUM ACETATE, PH=5.3, VAPOR DIFFUSION, SITTING DROP, temperature 293K
