The Specimen Repository stores more than three million specimen types from the AIDS Clinical Trials Group (ACTG) and the International Maternal Pediatric Adolescent AIDS Clinical Trials  (IMPAACT) Network. These include blood, serum, plasma, sputum, peripheral blood mononuclear cells, tissue, and other body fluids such as cerebrospinal fluid, semen, and endocervical and cervicovaginal lavage fluid.

To explore what is available, go to Search the Repositories. After choosing and submitting specimen options, there will be a results report with 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. If there is a need to search for options that aren’t listed you may request a custom search by going to here. You can then print, download, or link to the report, which can help you write a research proposal to either ACTG or IMPAACT. For more on this, read Submit a Proposal.
