Exosome Isolation From Cell Culture Media Protocol

Repeated ultracentrifugation steps can reduce the quality of exosome preparations leading to lower exosome yield.

Exosome isolation from cell culture media protocol.

Exosomes are involved in differentbiological processes including antigen. We show that concentration of cell culture conditioned media using ultrafiltration devices results in increased vesicle isolation when compared to traditional ultracentrifugation protocols. Uncompromising ev isolation delivers higher yields and cleaner preps. Each reaction can process 2 4 ml cell culture medium.

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. Leveraging our years of exosome expertise the sbi team has pushed exoquick tc extracellular vesicle ev isolation technology to new peaks of performance with exoquick tc ultra for tissue culture media and most biofluids. For 30 minutes to remove cells and debris. Isolation of exosomes can be a tedious non specific and difficult process.

2school of medicine university of queensland. No ultra centrifugation 2 hours 10 fold higher yield vs. Direct isolation of exosomes from cell culture. 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.

Centrifuge the cell media at 2000 g. Technical report optimized exosome isolation protocol for cell culture supernatant and human plasma richard j. Transfer the supernatant containing the cell free culture media to a new tube without disturbing the pellet. The yield of each reaction can yield pure exosome suspended in 50 200 µl pbs.

Transfer the required volume of cell free culture media to a new tube and add 0 5 volumes of the total exosome isolation from. Simplifying methods for exosome enrichment and analysis. 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.
