MFI for Particle Characterization of Biopharmaceuticals Today

November 26, 2013

Micro-flow imaging (MFI) is a sensitive, simple and automated method for the routine analysis of sub-visible particles and translucent protein aggregates. This technology provides particle size, count and morphology. Morphology provides the ability to discriminate a wide variety of particle types allowing you to monitor the change in both protein aggregates and other particles over time. This article reviews the application of MFI for monitoring protein aggregates and sub-visible particles in biopharmaceuticals.
