Information
Biology Centre of CAS – Institute of Parasitology and Faculty of Science – Institute of Physics and Biophysics, University of South Bohemia, České Budějovice, Czech Republic
This practical course is focused on the advanced methods of biological specimen preparation for electron microscopy. The main goal is to make participants familiar with the theoretical background and the latest practical developments in this field. The programme includes state of the art fixation, including cryo-methods, cutting of ultrathin sections from embedded or frozen samples, methods of negative staining and immunolabeling, specimen preparation for transmission and scanning electron microscopy and methods of specimen preparation for 3D electron microscopy (single particle analysis, electron tomography, array tomography and serial block-face). The results will be evaluated using electron microscopes. The course is limited to 15 participants. It is intended for Master and PhD students, young researchers, technicians, and new EM users. This course is supported by the program for large research infrastructures of the Ministry of Education, Youth and Sports within the project “National Infrastructure for Biological and Medical Imaging (Czech-BioImaging)“.
