Transfer the required volume of cell free culture media to a new tube and add 0 5 volumes of the total exosome isolation from. Direct isolation of exosomes from cell culture. Repeated ultracentrifugation steps can reduce the quality of exosome preparations leading to lower exosome yield. P100 kit is for exosome purification isolation at high yield and purity from cell culture media.

Total exosome isolation reagent from cell culture media enables simple and reliable concentration of intact exosomes from cell media samples with a protocol that is scalable depending on your sample size. The yield of each reaction can yield pure exosome suspended in 50 200 µl pbs. Exosomes 50 150 nm are extracellular vesicular structures secreted by cells in culture and found in body fluids 1. Exosomes are involved in differentbiological processes including antigen.

Centrifuge the cell media at 2000 g. We show that concentration of cell culture conditioned media using ultrafiltration devices results in increased vesicle isolation when compared to traditional ultracentrifugation protocols. Norgen s cell culture media exosome purification and rna isolation mini kit constitutes an all in one system for the purification of exosomes and the subsequent isolation of exosomal rna from different cell culture media sample volumes ranging from 5 ml to 10 ml. This chapter describes a detailed protocol for isolating exosomes from cell culture conditioned medium using ultracentrifugation and their characterization based upon size number and protein expression by several complementary methods such as transmission electron microscopy nanoparticle tracking analysis western blotting and flow cytometry.
