| Research Abstract |
The multi-step soaking method is a novel approach to the post-crystallization treatment used to improve quality of protein crystals. This new method improved the crystal quality of CagA, a type IV secretion effector derived from Helicobacter pylori, from 10 angstrom to 3.1 angstrom resolution. In addition, this method were applied to the other protein, and improved its crystal quality from 3.5 angstrom resolution to 2.1 angstrom resolution.
