Crystallization

Crystalization Experiments
Method Vapor Diffusion Hanging Drop
pH 6.5
Details CRYSTALS WERE GROWN IN HANGING DROPS WHICH INITIALLY CONSISTED OF 5.9 MG/ML PROTEIN IN 0.1 M HEPES BUFFER (PH 6.5) CONTAINING 8.3 MM S-HEXYLGLUTATHIONE AND 1.0 M BUFFERED (PH 6.5) AMMONIUM SULFATE. THE DROPS WERE EQUILIBRATED AT 293 K AGAINST WELL SOLUTION CONTAINING BETWEEN 1.9 - 2.0 M AMMONIUM SULFATE IN 0.1 M HEPES BUFFER (PH 6.5)., vapor diffusion - hanging drop
