Redman %J Journal of Extracellular Vesicles %D 2013 %I Co-Action Publishing %R 10.3402/jev.v2i0.19671 %X Nanoparticle tracking analysis (NTA) is a light-scattering technique that is useful for the rapid sizing and enumeration of extracellular vesicles (EVs). As a relatively new method, NTA has been criticised for a lack of standardisation. We propose the use of silica microspheres for the calibration of NTA measurements and describe in detail a protocol for the analysis of EVs by NTA which should minimise many of the sources of variability and imprecision associated with this technique. %K extracellular vesicles %K nanoparticle tracking analysis %K light scattering %K standardisation %U http://www.journalofextracellularvesicles.net/index.php/jev/article/view/19671/26035
