Size, concentration and surface charge
Nanoparticle Tracking Analysis
ZetaView® QUATT (Particle Metrix Inc.)
- Measuring hydrodynamic number average particle size, concentration and surface charge.
- Selective analysis of size sub-populations in the samples.
-
Enhanced fluorescence measurement capability. Multi-wavelength F-NTA allows assessing the purity of exosomes isolation, phenotyping of EVS, measurement of sEV dsDNA.
-
Virus and Virus like particles characterization, defined virions can be stained and thus identified from complex samples such as patient material. F-NTA can be used to analyze the amount of successfully loaded (nucleic acid-containing) virions.
