We hosted the 69th Symposium of the Japan Electrophoresis Society Symposium on October 25, 2019. The theme of the symposium was "Frontiers of cancer and sarcoma research and electrophoresis technology," and nine speakers who were active at the forefront of cancer research and electrophoresis technology gave lectures. Many doctors participated, and we were able to have a lively discussion on research aimed at eliminating cancer. Also, on the day we were able to hold a successful party with the help of many people. Thank you very much.
