The specimen repositories are a collaboration between several clinical trial networks to make the larger body of specimens collected for HIV research available to investigators.

The specimens stored at the repositories were initially collected for specific studies that have concluded, have been approved for use by network leadership and are now available to investigators conducting new research.

Using this website

You can use the interactive search tool on this website to learn about the types of specimens available at the repositories. After completing a search, you can see the number of specimens and unique participants available, information about the studies for which they were collected, and what research was published for those studies. The search tool will also provide you with a report that lists your specimens of interest. You can then use this report to help write your research proposal to the network.
