The National Cancer Institute is making its inventory of radiolabeled compounds available to qualified researchers. These radiolabeled drugs are available to qualified researchers from the Drug Synthesis and Chemistry Branch, DTP, DCTD, NCI.

Requests for radiolabeled compounds should be addressed to:

Dr. Prabhakar Risbood
Drug Synthesis and Chemistry Branch
National Cancer Institute
Executive Plaza North, Suite 8028
6130 Executive Boulevard, MSC 7448
Bethesda, MD 20892-7448

Phone: 301-435-9157 or 301-435-9159
Fax: 301-480-4817

Requestor must submit a brief description of the planned research and a justification of the need for the labeled material, a request should include the amount of radioactivity needed, and the required specific activity.

These requests are reviewed by an NCI committee for approval. The labeled compounds are provided free of charge to qualifying researchers. Qualifying researchers must have a valid radioactive materials license, and a copy of the license must be sent to the NCI and to the shipping contractor. Name and address of the shipping contractor will be provided upon approval.

In addition a duly signed Simple Letter of Agreement (SLA) available in html format or PDF format and Federal Express account # must be submitted along with the request. Requestor will bear the shipping.

INCOMPLETE REQUEST FORMS WILL NOT BE PROCESSED AND NOTIFICATION OF INCOMPLETENESS WILL NOT BE SENT.
