Refeyn specializes in mass photometry, a technique that measures the mass of single molecules in their native, unlabeled state. Its products are compact bench-top instruments coupled with automated software that enables rapid mass analysis from only a few microliters of sample. Researchers can obtain mass distributions in minutes without prior knowledge or labeling. The company differentiates itself through its native-state, label-free approach, user-friendly bench-top systems, and integrated software that streamlines data acquisition and interpretation, making advanced biomolecule analysis accessible to academic labs, research centers, and pharmaceutical companies. Refeyn aims to advance bioanalytics by providing practical mass measurement tools that uncover biomolecular properties and functions with minimal setup and sample requirements.

Simplify's Take

What believers are saying

  • AI-driven drug discovery expansion drives demand for pre-screening tools like MyMass.
  • Gene therapy manufacturing growth positions KaritroMP as critical AAV quality control.
  • 500th global installation across 30+ countries validates market penetration and adoption.

What critics are saying

  • Cryo-EM vendors integrate sample quality assessment, eliminating MyMass standalone value.
  • Competitors commoditize mass photometry with lower-cost single-particle alternatives within 18–24 months.
  • Pharma consolidation standardizes on incumbent platforms, causing post-acquisition customer churn.

What makes Refeyn unique

  • Label-free single-molecule mass measurement without inference from hydrodynamic radius.
  • MyMass compact instrument addresses sample quality bottleneck in cryo-EM and structural biology.
  • StreamlineMP automates high-throughput mass photometry data analysis for pharmaceutical workflows.

Refeyn launches MyMass instrument to simplify sample quality assessment for structural biology.

Refeyn launches MyMass instrument to simplify sample quality assessment for structural biology. GlobeNewswire Published Mar 18, 2026 Article content Compact, all-in-one mass photometer helps researchers verify sample quality before proceeding to cryo-EM, native MS, BLI, SPR, and other costly experiments Article content OXFORD, United Kingdom, March 18, 2026 (GLOBE NEWSWIRE) - Refeyn, developer of pioneering mass photometry technology, announces the launch of MyMass(TM) mass photometer (MyMassMP), a compact instrument designed to answer a critical research question: Is the sample good enough for further analysis? Article content Structure-based drug design and AI-driven therapeutic development are transforming how new medicines are discovered, but depend on high-quality samples. Structural and biophysical workflows, such as cryo-EM, native mass spectrometry (MS), bio-layer interferometry (BLI), and surface plasmon resonance (SPR), are time-consuming and costly, and poor sample quality remains one of the main reasons they fail. MyMassMP gives researchers a fast, accurate assessment of purity, homogeneity, and oligomerization state in solution before committing to resource-intensive experiments. Article content Advertisement 1 Story continues below Article content Built on the same proven technology as Refeyn's TwoMP mass photometer, which is already trusted across leading structural biology and biotherapeutics labs worldwide, MyMassMP brings this quality check capability into a simpler, self-contained benchtop instrument. Featuring an integrated display and computer for onboard data analysis, and dedicated consumables, it offers an intuitive workflow from sample to result.

Article content "Structural biology and AI-driven drug discovery are moving fast, but they're only as good as the samples that drive them. MyMass directly addresses that challenge and marks a significant step forward for Refeyn, putting the power of mass photometry within reach of more researchers than ever before," said Gerry Mackay, Refeyn CEO. Article content Fiona Coats, Chief Product and Marketing Officer at Refeyn, said: "In recent years, our users have consistently shown us how valuable mass photometry is for quickly assessing sample quality before committing to more complex experiments. With MyMassMP, we're making this capability even more accessible - empowering researchers to confidently answer a simple but critical question: Are my samples ready?"
