Covid Calls

Vaccine Scheduling Update: We’re experiencing very high call volumes from people interested in getting the COVID-19 vaccine. Currently, our vaccine supply is very small, and we are unable to accept phone calls to schedule vaccine appointments. Please check back here for updates.

The Molecular Pathology and Imaging Core is a resource for researchers at Penn, CHOP, and beyond.  We offer histological services, equipment, and technical expertise to assist in a variety of research projects.

We are located at 931-933 BRB II/III.  Please contact an MPIC team member if you have any questions or would like to submit an order.

MPIC is funded by the Center for Molecular Studies in Digestive and Liver Diseases (NIH P30 DK050306).

Ordering and Pricing

How to Submit Samples

Please place an order using our online tissue order form here.  Specimen IDs’ should be listed in vertical format with one ID per line.

Please create a Unique ID for each sample, 15 characters or less.  We batch process samples and are not responsible for mix-ups if there are duplicate identifiers between your samples and previously submitted samples, other lab members' samples, etc.  We recommend you label each sample with its unique ID on the front and side of the cassette, using either a pencil or a chemical resistant pen.  

Samples should be pre-fixed in individual cassettes, then transferred to a container filled with 70% EtOH and labeled "PI's last name/Contact name” prior to drop off in cold room 965. It is difficult to return glassware so MPIC users are welcome to borrow a beaker.  If providing slide boxes, please drop them off on the shelf labeled "Slide box drop off" in 931 BRB.

You will receive an email when your order is complete and ready to be picked up.

Please contact an MPIC staff member if you have any questions or concerns about submitting your order.

Molecular Pathology & Imaging Core Services are available at subsidized prices to AFCRI Members and Members of the Center for Molecular Studies in Digestive and Liver Diseases. Center Member Application (Word doc)
