The NCI story is a Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) "Success Story" featuring Stellar's technology platform, NCI SBIR awards and recent corporate partnerships.

The NCI's prestigious SBIR and STTR programs "foster research and development for anticancer agents, biomarkers, informatics, medical devices, nanotechnology, proteomics, pharmacodynamics, and many other biotechnologies and programs designed to prevent, diagnose, and treat cancer."

Popular Science magazine's article "How Mollusk Blood Could Cure Cancer" covered the role of keyhole limpet hemocyanin (KLH) as an essential component in cancer vaccine research and Stellar's sustainable aquaculture practices.

Stellar notes that the Popular Science story included one error. Contrary to the article's report, Stellar's current manufacturing capacity (not output) is between one and two kilograms of KLH per year.
