The U.S. Environmental Protection Agency (EPA) is offering a Technology Transfer Licensing Opportunity for its innovative "Retention Lid for Cell Culture Inserts," aimed at enhancing the stability of porous membrane inserts (PMIs) used in various scientific fields. The EPA seeks companies interested in licensing this government-developed technology to further commercialize, manufacture, and market the Retention Lid, which prevents unintentional shifting of PMIs during cell culture manipulations, thereby reducing errors such as reagent overflow and media contamination. This technology is crucial for improving laboratory practices in toxicology, oncology, and other disciplines, ultimately conserving resources and ensuring experimental accuracy. Interested parties can find more information and submit a license application form through the EPA's Federal Technology Transfer Act team at ftta@epa.gov, with no funding provided to licensees and patent protection pending for the technology.
