    The FACS core facility consists of three FACS instruments (BD LSRFortessa, FACSCantoII, FACSCalibur) and two sorters (BD FACSAria Fusion and FACSAria I). Dr. Stefan Stein oversees the performance of the FACS facility and is available for scientific questions regarding flow cytometry in general and the establishment of new FACS based assays. Annette Trzmiel is responsible for high-speed cell sorting as operator in this central service unit for all working groups of the GSH as well as external research groups. She also takes care of the maintenance/functionality for the flow cytometers in the institute. Occasionally Thorsten Geyer serves as an additional FACSorting operator.
