Abstract
Described herein are novel rapid and reliable methods of detection of extracellular vesicles and quantifying extracellular vesicle concentrations and absolute number from various sources, including raw cell harvest. The methods described herein comprise detection of light scattering of extracellular vesicles in biological samples.
