Crystalization Experiments
Method Vapor Diffusion Hanging Drop
pH 7.5
Details HANGING DROP VAPOR DIFFUSION. 10-15 MG/ML PROTEIN IN 50 MM TRIS-HCL, 0.5 M NACL, 10 MM MGCL2, 5MM GTP, 2 MM EDTA, 4 MM DTT, PH 7.5 WERE MIXED WITH AN EQUAL VOLUME OF AND EQUILIBRATED AGAINST 100 MM TRIS- HCL, 200 MM NACL, 200 MM AMMONIUM SULFATE, 34% MEOPEG 5000, PH 7.5. THE CRYSTALS WERE SOAKED IN EQUILIBRATION SOLUTION WITH 100 MM MANGANESE(II)CHLORIDE AND 5 MM GTP FOR 4 HOURS PRIOR TO DATA COLLECTION., vapor diffusion - hanging drop
