Multiple aliquots of GTEx tissues have been made available to the scientific community through a Request for Application funding mechanism (http://grants.nih.gov/grants/guide/rfa-files/RFA-RM-12-009.html) and a biospecimen access policy has been developed for already-funded investigators (http://www.gtexportal.org/static/form/GTEx_sample_access_policy_to_the_public_v20131024.doc). In addition, 40 SOPs from the GTEx project are available for public use and are a major contribution to the research biobanking community (http://biospecimens.cancer.gov/resources/sops/default.asp).
