Scheduling and Fees

Facility Hours

Investigator-operated analysis instruments are available year round, 24 hours/day. Not all instruments are available to non-Wistar investigators; contact facility personnel for information.

Resource personnel are generally available 9:30 AM – 5:30 PM, Monday through Friday. Their hours can be extended (with 24-hour advance notice) until 7:30 PM or beyond to accommodate individual experiments. Requests for hours extended beyond 7:30 PM will be considered on a case-by-case basis.


User-friendly analysis instruments are available to Wistar personnel only, and may be scheduled through the Wistar Intranet.  You will need a valid username and password to access the Flow Cytometry Calendar, found in the right-hand column on that page.  These instruments are available to only those who have received approval from the facility (contact the facility for details). You may view, but not schedule or modify sorting appointments as well.

Scheduling appointments for operator-assisted analysis or any sorting may be done in person (Room 480, Hill) or by telephone (215-898-3811*). E-mail is not an acceptable method for making these appointments. All appointments must be confirmed by one of the operators. Consulting/training or other inquiries may be made via email.

  * University of Pennsylvania investigators must dial all 10 digits when calling Wistar.

Facility personnel must be contacted prior to the planning of an experiment requiring
their assistance. Information to be provided generally includes:
● number of samples (including all controls) to be analyzed;
● type of samples and staining;
● actual time of arrival in the facility;
● if sorting, number of cells per sampled to be sorted.

This multi-user facility runs on a tight schedule. It is imperative that you be on time for your appointment, with only as many samples as had been scheduled. If you will be late, need to increase the number of samples, or wish to cancel your appointment, please contact the facility as soon as possible to avoid being charged.


Many different samples from various sources that may contain known or unknown human pathogens are investigated in the Flow Cytometry Facility. In general, the facility cannot accommodate any BSL3 material – all BSL3 samples must be appropriately inactivated through fixation prior to analysis or sorting.  Information about the sample sources and potentially infectious agents is critical for effective biosafety measures.  Consequently, a sample information form must be completed and signed by the Investigator who is requesting samples to be sorted prior to scheduling.  Contact facility personnel to discuss biosafety considerations or to request a form, or use this Biosafety Form.
