About Refeyn

Refeyn Ltd. specializes in the development, production, and distribution of mass photometry technology for industry and academia. Mass photometry is a unique bioanalytical technology pioneered by Refeyn that enables the measurement of molecular mass at the single-particle level by quantifying light scattering from biomolecules in solution. Spun out of Oxford University in 2018, the company aims to make mass photometry accessible to all in the scientific community, enabling users to achieve new and better outcomes. Refeyn has been recognized for its unique approach to biomolecular analysis through multiple awards, including the Royal Society of Chemistry Emerging Technologies Competition. Applications of mass photometry include: sample characterization and analysis of protein oligomerization, biomolecular interactions, and macromolecular assemblies. Utilizing the novel technology of mass photometry, Refeyn’s products are capable of accurate mass measurement of single molecules in solution, in their native state, and without the need for labels, opening up new possibilities for bioanalytic and research into biomolecular function.
