What you will learn, at a glance 

• The KaritroMP macro mass photometer uses multiparametric analysis to resolve and quantify populations in heterogeneous samples  

• By leveraging simultaneous single-particle measurements of size and contrast (a proxy for mass), macro mass photometry (MMP) provides far greater resolving power than NTA or DLS 

• MMP characterizes the size and contrast of each population, as well as its abundance 

• Its speed, low sample consumption, and ability to effectively resolve heterogeneous populations make MMP a powerful tool for characterizing large viral vectors, like AdV and LVV
