| Outline of Final Research Achievements |
Making full use of a conventional fluorescent microscope system, we tried chemiluminescent live-cell imaging for the stably expressing cell lines which we introduced the BAF (BRET-based Auto-illuminated Fluorescent-protein)-fusion proteins that are our own technique into, and showed the possibility of the chemiluminescent live-cell imaging based on luciferin - luciferase reaction. In the experiments, we found some problems newly. A major problem was the air bubbles dependent on the required culture medium ingredient and caused by a perfusion process in the closed live-cell micro-observation chamber system. We tried the development of the device to remove the air bubbles based on the simple principle concerned, but did not lead to completion during the research period. Meanwhile, for the purpose of a higher intensity of eBAF-Y, we found a new approach to achieve a higher efficiency of the resonance energy transfer which happens in the BAF molecules, and applied for a Japanese patent.
