| Research Abstract |
We have been studying a new technique “plasma-assisted biological macromolecular crystallization”. Improvement in the crystallization probability of biological macromolecules by plasma irradiation had been reported with lysozymes from hen egg whites. For understanding the mechanisms, we studied decolorization process of various dyes indicating the reaction speed by their color change. The reaction speeds largely depend on pH of the solution and the dependency is not unique. The results suggest that, for useful application of the new crystallization technique, the conditions of solution should be considered properly.
