Heart–lung machine and ECMO systems for cardiopulmonary support during complex experimental interventions. Organizational context and availability Located at Campus Virchow-Klinikum as part of the Forschungseinrichtungen für Experimentelle Medizin and operated in cooperation with the Deutsches Herzzentrum Berlin. Provides core facility research infrastructure of the Charité faculty for translational cardiovascular research and advanced training in a large-animal setting. Certified according to ISO 9001:2015, indicating a documented quality management system for its services.

Facility for high resolution imaging of biological samples at cryogenic temperatures. Amongst other applications such as single particle data collection, our high-end instrumentation is suited to perform in situ structural biology by combining cryoCLEM, lamella FIB-milling, and cryo-electron tomography.

Core provides services supporting generation, modification, cryopreservation, and rederivation of genetically modified rodent models for biomedical research, generates genetically modified mouse models via both targeted and random mutagenesis using tools such as CRISPR/Cas9 in zygotes or embryonic stem (ES) cells, provides cryopreservation and rederivation of existing animal models to preserve hygienic integrity. Services for rodent transgenic model development include: Pronuclear Injection and amp; Viral Transgenesis with introduction of genetic constructs into zygotes using microinjection or lentiviral systems; ES Cell-Based Techniques: use of embryonic stem cell manipulation for genetic targeting; Embryo Transfer: transferring manipulated embryos into recipient females; In Vitro Fertilization (IVF): assisted reproductive technology to generate embryos for manipulation or cryopreservation; Cryopreservation: freezing of embryos and sperm for archiving or rederivation of lines as required. Facility’s expertise includes quality control of cryopreserved material to ensure viability upon thawing.

We generate a broad range of viral vectors, including lentiviruses, AAVs, retroviruses, SFV, VSV, adenoviruses, and rabies viruses.

The Viral Core Facility (VCF) of the Charité – Universitätsmedizin Berlin provides comprehensive services for the generation of viral particles to Charité researchers as well as external academic (non-profit) institutions.

Our activities encompass a full DNA vector service for the design and generation of new plasmids, a dedicated production unit for viral particle generation, and an analytical platform for the characterization and quality control of viral preparations.

In addition, we provide an online catalog that offers an overview of our available viral tools and standardized vectors, facilitating project planning and selection of suitable constructs.

The Charité Experimental MRI laboratories at Charité Campus Mitte offer two 7 Tesla Bruker MRI machines for preclinical research. Users have access to a wide range of established methods in the field of neuroimaging of anatomy, tissue microstructure, structural/functional connectivity, but also in the field of functional and molecular MRI of tumors, kidney, placenta or heart.

ZeBanC is an integrated healthcare biobank that operates under certified conditions and strict SOPs. This enables biomedical and translational researchers to perform their analyses using high-quality biospecimens and data to generate reliable and reproducible research data. To meet the needs of our various stakeholders, we offer a modular biobanking portfolio that can cover the entire workflow from blood collection to storage, including all pre-analytical steps and their documentation. This includes access to existing biospecimens and data under well-defined and agreed conditions. Furthermore, we offer a spectrum of additional services ranging from DNA/RNA extraction and virtual microscopy to the entire management of sample and data flow for national/international research consortia. Last but not least, we provide secure conventional and automated storage of samples at various temperatures as well as secure data management.
