| Outline of Final Research Achievements |
The fluid reaction transmission electron microscopy (FR-TEM), which can directly observe inside liquids at nano-scale and in real time, was applied to crystallization of lysozyme protein in a solution.
By optimizing the crystallization condition, in-situ observation of crystallization of lysozyme was successfully performed. Two crystalline phases (orthorhombic and tetragonal) and an amorphous phase coexisted at nano-scale under the solution condition. The moment of the nucleation of orthorhombic lysozyme crystal was successfully captured.
