ARPAH is seeking innovative solutions for stabilizing regenerative tissues and organs through enabling technologies for temperature-flexible storage. The TIGAR exploratory topic has two intake groups with deadlines for solution video and full proposal submissions in 2026 and early 2027. Total ARPA funding requested must not exceed $2 million USD over an 18-month period of performance. Proposers must demonstrate progress towards functional preservation of tissues or organ subunits at practical temperatures. Universities, non-profit organizations, small businesses, and other commercial entities are encouraged to respond. Registration in SAM. gov is required. Late submissions due to registration delays will not be considered.
For intake group 1, the solution video submission deadline is August 12, 2026, and the full proposal submission deadline is September 17, 2026. For intake group 2, the solution video due date is December 8, 2026, and the full proposal due date is February 5, 2027. The ISO closing date is February 5, 2027.
Performers will be required to register in and submit invoices for payment through the Payment Management Services (PMS) at www. ***. *. * must include a justification limited to 1,000 characters.
Full proposals will be evaluated based on overall scientific and technical merit, proposer's capabilities and/or related experience, contribution to the ARPAH mission and relevance to the user experience, and assessment of proposed cost/price.
Eligible proposers include universities, non-profit organizations, small businesses, and other commercial entities. Federally Funded Research and Development Centers (FFRDCs) and government entities are generally not eligible as prime or sub-performers, unless they possess unique capabilities. Individuals and entities providing current professional support services to ARPAH are ineligible. Foreign entities may participate if they comply with applicable regulations.
Nonconforming submissions that do not follow ISO instructions or are out of scope may be rejected. Failure to obtain or maintain an active SAM. gov registration may delay or preclude award. Failure to fully disclose an OCI or provide requested information may lead to proposal rejection. Failure to provide requisite research security disclosures or mitigate research security risks may eliminate a proposal from award consideration.
The total ARPA funding requested must not exceed $2 million USD over the 18-month period of performance.
