The core technique of our facility is Synchrotron Radiation Protein Crystallography, a technique that uses the principle of single crystal X-ray diffraction to determine high-resolution three-dimensional protein molecular structure from a protein crystal. It is the most powerful and important method to study biological structures. Currently, nine out of every ten biological structures are solved by this technique. Worldwide, only 18 countries and the European Union possess synchrotron radiation facilities and provide protein crystallography technique, and Taiwan is included. Being the only facility in Taiwan that provides this technique, our goal is to build a world-class protein crystallographic facility to assist industrial and academic scientists and experts in the field of biomedical science (including structural biology, proteomics, biochemistry, molecular biology, drug design, biotechnology, etc.) to develop prevention, diagnosis, and treatment of various diseases. That helps improve the health of people, increase the quality of life and effectively conserve medical resources.
