Is it possible to measure the proteolytic activity of proteins on the surface of exosomes that were isolated with ExoEasy?

The exoEasy Maxi Kit uses membrane affinity spin columns to efficiently isolate exosomes and other extracellular vesicles from serum, plasma, cell culture supernatant and other biological fluids. The maxi column format allows the use of large sample volumes, including up to 4 ml plasma or serum or up to 32 ml cell culture supernatant. The procedure is very fast, consistent and highly suited for isolation of EVs for functional analysis of exosomes and other extracellular vesicles.
