This repository, an NCI-sponsored facility, stores bulk cytokines, monoclonal antibodies, and cytokine standards under carefully controlled conditions. The repository provides a constant and uniform supply of high-quality reagents to nonprofit institutions and qualified commercial establishments at no charge. This facility obtains new materials by donation or at reduced cost by negotiating with companies and investors. To date, the Biological Resources Branch Preclinical Repository has distributed more than 40,000 samples, and the estimated value of materials shipped to investigators is about $100,000 per year.
