Microscopy and Flow Cytometry Core
Geisinger Commonwealth School of Medicine’s Microscopy and Flow Cytometry Core supports the research of investigators and their trainees. It provides all levels of technical support and consultation for researchers needing imaging of cells and tissues, flow cytometry analysis of protein expression on cells or cell cycle analysis and cell sorting. The facility furnishes techniques and instrumentation to investigators and laboratory personnel for research and training.

General procedures for the core
The Flow Cytometry Core Facility is for research use and must be scheduled in advance for use. Billing for usage is completed monthly by department and principal investigator. We do not break down the billing by technician or project, but if the researcher needs this information, they can retrieve it upon request to the core facility. All users must schedule time on the calendar, whether in advance or as a walk-in (depending on availability). The facility is designed to have the users operate the instruments when running samples and analyzing data; however, services are offered. The core personnel will train these users to become proficient over time in setting up their experiments, running samples and producing and archiving data resulting from the experiments. There is a terabyte server available to all researchers for transferring data to your laboratory for archival or further analysis. Users may also transfer data to other portable storage media if desired. In any case, the user is ultimately responsible for archiving any and all data generated. Safety for all users and core personnel is a priority concern. Since the core facility is a shared laboratory and is designated as a BSL II facility, there are certain guidelines that all users are responsible to be aware of and follow. This is a special concern for cell sorting and biosafety concerns and guidelines will be strictly adhered to. This policy is summarized in our safety guidelines, available to all new users. They include guidelines for the safe use of lasers as well.

Citing the core in publications
When using data or tools generated at Geisinger Commonwealth in publications or grants, cite the core laboratory personnel who worked on the project and the “Microscopy and Flow Cytometry Core Facility, Geisinger Commonwealth School of Medicine” as appropriate. Also let research leadership know about publications or grant applications that make use of the services of this facility – this is important for continued availability of these services.
