Refeyn revolutionizes biomolecular analysis. Measure the mass of single molecules label-free, in their native state, and get critical insights into purity, interactions, and heterogeneity – faster than ever before.
As of May 26th, our consumables pricing has changed, and our catalog has been adjusted to better meet your needs. These updates are based on the valuable feedback you provided in our survey earlier this year.
Thank you for helping us improve!
Our technology uses light scattering to measure the mass of individual molecules and viral capsids with accuracy and precision. Here’s a simplified look at the process.
Our technology is transforming research in a wide range of fields.
Precisely characterize AAV preparations by accurately determining empty versus full capsid ratios, aggregation states, and overall integrity. Crucial for optimizing production and ensuring the safety and efficacy of gene therapies.
Gain direct, label-free insights into AdV quality by assessing particle concentration, aggregation, and purity. This enables better control over manufacturing processes for gene delivery vectors and oncolytic agents.
Accurately detect and quantify antibody aggregates in solution – faster and with far less sample than SEC and AUC. Essential for optimizing formulation conditions, improving stability, and ensuring safe, effective biotherapeutics.
Comprehensively profile bispecific and multi-specific antibody-antigen interactions, including stoichiometry. Ideal for new modalities, complements SPR and BLI, aiding experimental design and the interpretation of data on multi-component systems.
Analyze membrane proteins in native-like environments, determining oligomeric states, complex formation, and sample purity. Critical for advancing structural studies, functional assays, and therapeutic development.
Characterize mRNA integrity and its formulation in lipid nanoparticles (LNPs). Assess size distribution, encapsulation efficiency, and stability of mRNA-LNP complexes, vital for developing and quality controlling mRNA-based vaccines and therapies.
Directly measure complex formation, stoichiometry, and binding strength to reveal how proteins interact in solution. Vital for understanding biological mechanisms, validating targets, and accelerating drug discovery.

ABL Europe
We’re generating data to compare mass photometry with gold standards like AUC and cryoTEM. Early indications show that it’s much quicker and equally accurate. Partners who’ve compared mass photometry to other methods themselves vouch for its accuracy. It’s a game changer in AAV characterization, for us as well as our clients.
