Figure 1: Typical profile of CRISPR-Cas9 genome edited mES cell lines for single cell sorting. The facility provides key services, such as sorting heterogeneous cell populations into homogeneous populations based on fluorescence.
The facility provides access to state-of-the-art and project dedicated analysis and cell sorting instrumentation.
We offer a wide range of flow cytometric techniques, hands-on service, data analysis and tailored training sessions for users from inside and outside EMBL. Our specialised equipment adds flexibility in the preparation and execution of experiments, allowing tailored approaches to addressing scientific problems. Our facility strives to meet researchers’ specific needs by providing dedicated help with experimental design, enabling the highest possible resolution in terms of analysis and product. We have recently upgraded the facility to provide access to S2 cell sorting services and improved our general sorting setup to meet the growing need for high-parametric and aseptic sorting.
We work with equipment from Beckman Coulter, Becton Dickinson, Union Biometrica, Coherent Inc. and ThermoFisher. The EMBL Flow Cytometry platform is open to test new technological developments to best serve the needs of the scientific community.
Major projects and accomplishments
