Nanoparticle tracking analysis (NTA) technology is a routine light scattering method to characterise extracellular vesicle (EV) sub-populations for consistent and reliable results. This NTA service is carried out at the Cell Guidance Systems laboratory with full reports sent in 5-10 working days.
NTA is a technique used for the simultaneous measurement and analysis of the size and concentration of single nanoparticles with high precision, accuracy and reproducibility.
A laser is directed at the sample solution which generates light scattering by the particles in the sample. The NTA software captures the Brownian motion of each individual particle in a recorded frame-by-frame video. Large and small particles have different diffusion movements in solution which allows for the measurement of the hydrodynamic diameter of each particle using the Stokes-Einstein equation.
Exosome characterisation with NTA
Exosomes have been isolated using the Exo-spin™ kit and analysis performed with the ZetaView® instrument.
