The Ultrastructural Technology Platform comprises two essential components: the subcellular ultrastructural imaging technology platform and the single-particle protein structure analysis technology platform. Subcellular ultrastructural imaging technology platform is crucial for analyzing the ultrastructure of organelles within cells. By providing detailed insights into the organization and function of cellular components, this technology aids researchers in understanding cellular processes and their implications for health and disease. Single-particle protein structure analysis technology platform addresses the need for three-dimensional spatial structure reconstruction of biological macro-molecules. It is instrumental in structural biology, enabling researchers to visualize and analyze the intricate structures of proteins at the atomic level.
