Eight ways mass photometry is accelerating biological discovery

Mass photometry and macro mass photometry are powerful bioanalytical techniques that are being adopted across the life sciences. From academic researchers to CDMOs and leading biopharma companies, many have harnessed […]
Making sense of mass photometry measurements (2025)

Mass photometry is a novel way to measure the mass of biomolecules. It works by quantifying the light scattered by an individual molecule in solution, which is directly proportional to the molecule’s mass [1], [2] (read more about how mass photometry works).
Transforming adenovirus (AdV) vector analysis with macro mass photometry

Adenoviral vectors (AdV) are widely used as effective delivery platforms for vaccines, gene therapies and cancer treatments. In order to ensure these therapeutic products are safe and effective, critical quality […]
Mass photometry: The perfect team player for antibody analytics

Antibodies are powerful therapeutics used to treat a range of diseases, which is being expanded thanks to the development of new engineered formats like bispecifics. However, developing new antibodies comes […]
Characterization of Iodixanol purified AAV samples
