Schröder1,2,3 1Cryo Electron Microscopy, Centre for Advanced Materials, Universität Heidelberg, 2Heidelberg Karlsruhe Research Partnership (HEiKA), 3Cryo Electron Microscopy, BioQuant, Universitätsklinikum Heidelberg, 4Institute for Automation and Applied Computer Science, Karlsruhe Institute of Technology (KIT), 5Carl Zeiss Microscopy GmbH, 6Electron Microscopy Core Facility, Universität Heidelberg This protocol targets specific cells in tissue for imaging at nanoscale resolution using a scanning electron microscope (SEM). Large numbers of serial sections from resin-embedded biological material are first imaged in a light microscope to identify the target and then in a hierarchical manner in the SEM.
Engineering and Evolution of Synthetic Adeno-Associated Virus (AAV) Gene Therapy Vectors via DNA Family Shuffling Eike Kienle*1, Elena Senís*1, Kathleen Börner2, Dominik Niopek1, Ellen Wiedtke1, Stefanie Grosse1, Dirk Grimm1 1Cluster of Excellence CellNetworks, Department of Infectious Diseases, Virology, Heidelberg University, 2Department of Infectious Diseases, Virology, Heidelberg University We demonstrate the basic technique to molecularly engineer and evolve synthetic Adeno-associated viral (AAV) gene therapy vectors via DNA family shuffling. Moreover, we provide general guidelines and representative examples for selection and analysis of individual chimeric capsids with enhanced properties on target cells in culture or in mice.
