The National Institutes of Health (NIH) is offering a funding opportunity titled "Assay Validation of High Quality Markers for Clinical Studies in Cancer" through a cooperative agreement mechanism (UH2/UH3). This initiative aims to support the validation of molecular, cellular, and imaging biomarkers essential for cancer detection, diagnosis, prognosis, and treatment response monitoring, with a focus on both analytical and clinical validation phases. The funding is intended for projects that demonstrate a working assay on human samples and justify its clinical relevance, fostering multi-disciplinary collaborations among scientific investigators, oncologists, and clinical laboratory scientists. Interested applicants should note that the application deadline is October 14, 2026, and can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
