Refeyn

Refeyn Ltd. specializes in the development, production, and distribution of mass photometry technologies for industry and academia. Mass photometry and macro mass photometry are unique bioanalytical technologies pioneered by Refeyn. By quantifying light scattering from particles in solution, mass photometry enables the measurement of molecular mass at the single-particle level while macro mass photometry enables simultaneous measurement of viral vector size and contrast (a proxy for mass).

Spun out of Oxford University in 2018, the company aims to make its technology 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: Characterization of samples of biomolecules and viral vectors, and analysis of protein oligomerization, biomolecular interactions, and macromolecular assemblies. Utilizing the novel technologies of mass photometry and macro mass photometry, Refeyn’s products are capable of accurate analysis of single particles in solution, in their native state, and without the need for labels, opening up new possibilities for bioanalytics.
