Label free  •  In solution  • 

In native state • Fast results

Mass photometry is a revolutionary new way of analysing proteins and other biomolecules. 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 protein research.
