Mass photometry is a revolutionary new way to analyse molecules. It enables the accurate mass measurement of single molecules in solution, in their native state and without the need for labels.

The mass histogram is acquired from a minute amount of sample in minutes. The ability of mass photometry to yield rapid and intuitive feedback on a variety of applications opens up new possibilities for bioanalytics and research into the functions of biomolecules.

A broad range of applications

Antibody oligomerization

Protein oligomerization



Biomolecular interactions


AAV therapy

Macromolecular assemblies

Antibody stability

Sample characterization
