Mass photometry is a widely used, label-free, single-molecule analysis technique that works by detecting the light scattered by a single particle at a glass-water interface. A single protein exhibits ...

These chains are compounded from a variety of small molecules which can modify the mechanical behavior of the polymer and skew its molecular weight. This makes it almost impossible to establish a ...

The studies presented in this article compare the use of mass photometry to size exclusion chromatography (SEC) - the industry’s gold standard - for the analysis of protein abundance and antibody ...
