Electron Microscopy and Histology Facility (EMH)
Center for Molecular and Cellular Bioengineering
The Electron Microscopy and Histology Facility provides expertise and technology to study the histology and ultrastructure of cell and tissue samples. The EM Facility offers access to modern sample preparation technology as well as to transmission and scanning electron microscopes (TEM and SEM), it also provides EM services, which are performed in collaboration with the reserach groups. The Histology Facility provides expertise and technology for the histological analysis of tissues, embryos and small animals. It offers access to sample preparation technology for paraffin or resin embedding, and to different types of microtomes for cryo- and room temperature sectioning. It also provides services such as embedding, sectioning, and staining (different histological stains, immunostaining). The facility constantly improves sample preparation methods and adapts them to new sample types. It also develops new sample preparation techniques especially for correlative and multimodal microscopy approaches (e.g. CLEM).
