Cutting-Edge Flow Cytometry & Cell Sorting

The Flow Cytometry Core provides a centralized resource of state-of-art equipment and expertise for multi-color flow cytometry and cell sorting services. Specialized staff assists users with experimental design, equipment optimization and operation, and data analysis.

The Flow Cytometry Core is supported by the Center for Cancer Biology (NIGMS CoBRE P30GM145398).

COBRE Funding Acknowledgment & Foreign Component Policy

Use of COBRE-supported Core facilities is intended to support research that complies with NIH requirements for COBRE awards, including restrictions related to foreign components.

What this means for your publications:

  • COBRE support may be acknowledged only when the work is fully compliant with NIH policy
  • NIH has clarified that collaborations with investigators at foreign institutions resulting in co-authorship are considered a foreign component
  • Because foreign components are not allowable under COBRE awards, publications that include foreign co-authors should not acknowledge COBRE support

Before publishing:

  • Confirm that COBRE funding can be appropriately attributed to your work
  • If you are unsure, please contact the Tracey McMahon prior to submission: Tracey.McMahon@sanfordhealth.org  

COBRE Core facilities do not determine authorship decisions; however, it is the responsibility of the investigator to ensure that acknowledgment of COBRE support is appropriate and compliant with NIH policy.

 

For full details, please refer to the COBRE Foreign Component Policy
