Comparison of methods for separating fluorescently labelled placental extracellular vesicles from free stain.
PLACENTA(2021)
Abstract
The field of extracellular vesicles (EVs) is relatively new and the methods for EV isolation and quantification are still maturing. For example, there is no consensus on how to separate free stain from labelled EVs. Here we report a comparison of the recovery of labelled EVs following separation from free stain using ultracentrifugation, diafiltration with different devices and a charged size exclusion chromatography column. Of the methods we tested, the charged size exclusion column provided the greatest recovery of labelled EVs.
