Biomarker Co-localization Measurements (C-NTA) Using the New Particle Metrix ZetaView x30 Family

Sven Rudolf Kreutel, Sales Director, Particle Metrix GmbH

During the last decades, Nanoparticle Tracking Analysis (NTA) has emerged as a vital and fast characterization technology for biological nanoparticles like Extracellular Vesicles, Exosomes and Viruses. While classic NTA scatter operation feeds back particle size and total concentration, the fluorescence detection capability enables the user to gain specific biochemical information. Determination of biomarker co-localization however, is a challenging task for any analytical instrument. A new laser generation ensuring perfect overlap of the illumination volumes of individual channels paired with very fast switching times between fluorescence channels lay the foundation of co-localization nanoparticle tracking analysis (C-NTA) introduced recently by Particle Metrix. For the first time, we report results of co-localization measurements of reference material as well as real biological samples based on NTA technology on the new ZetaView® PMX-230 TWIN.
