Outline of Final Research Achievements

Each of the biological phenomenon or functions of our body is generated by the interaction among molecules at subcellular and cellular levels. Thus, in order to deepen our knowledge about underlying mechanisms for the biological phenomenon and to develop new therapeutic approaches for diseases, it is important to uncover quantity (expression density) of individual bio-molecules at nano-scale spatial resolution. However, it is not possible to obtain such information by conventional molecular localization techniques. Here in this research project, I introduced several optimizations in SDS-digested freeze-fracture replica labeling and revealed localization of several ion channels in neuronal plasma membrane.
