What do we do?

TAS provides access to diagnostic paraffin block archives for research purposes. The OSU Department of Pathology's collection of archival specimens dates back to 1968, which is comprised of approximately 600,000 cases. Access to these specimens for clinical trials and research requires IRB approval. All blocks are retained by the TAS and only made available to Pathology Core Facility (PCF) for subsampling.

Steps to access services :

• Contact TAS staff.
• Discuss the project.
• Submit application request, IRB status and billing information.
• TAS staff conducts computer generated searches of available cases.
• Slides (H&E) are pulled and reviewed by a pathologist.
• Paraffin blocks are selected.
• TAS staff sends blocks to lab for cutting/processing.
• Processed specimens are returned to the TAS.
• Information regarding processed material is sent to the investigator.
• Distributed to the investigator.
