Phase I Research Support

The Comparative Pathology Core will resume all Phase 1 research support activities on June 8, 2020.

Please be aware that while we accept requests from all labs campus-wide, investigators who are not Penn Vet employees are not allowed to access the CPC's facilities during Phase 1.

For this reason, a contact-free sample drop off/pick up point has been arranged in the Hill Pavilion lobby (380 South University Avenue, Philadelphia PA, 19104). Access to the Hill Pavilion will be allowed with a valid Penn ID on Tuesdays and Thursdays from 9 AM to 1 PM

Detailed guidelines on how to drop off/pick up samples

  • Drop-Off
    • Inform our staff members that you intend to submit samples. To do so, please send an email to Juli Burns (jmburns@vet.upenn.edu) and Brona Ranieri (brona@vet.upenn.edu) including the 4 digit CPC service request number as reference.
    • Bring the samples to the lobby of Hill Pavilion (380 South University Avenue, Philadelphia PA, 19104) during the available time slots (Tuesdays and Thursdays from 9 AM to 1 PM).
