Exosomes are small membrane vesicles (30–150 nm) of endocytic origin, which are shed by all cell types under normal- and patho-physiological conditions. Exosomes have pleiotropic physiological and pathological functions and play significant roles in diverse pathological conditions such as cancer, infectious and neurodegenerative diseases.
Exosomes have received significant attention for their roles in pathobiological processes and are being explored as a tool for disease diagnosis and management. Consequently, various isolation methods based on different principles have been developed for exosome isolation such as differential ultracentrifugation, density gradient ultracentrifugation, ultracentrifugation, chromatography, magnetic bead immunoassay, polypolymer precipitation method, etc. However, the quick and easy operation of exosome isolation kits is irreplaceable.
CUSABIO Exosome Isolation Kits purify exosome by affinity purification. High Purity exosomes and other Evs (Extracellular vesicles) from cell culture medium and body fluid (high yield by normal microfiltration) can be easily obtained by this method.
The experiments include Transmission electron microscope analysis, Nanoparticle tracking analysis, NanoFCM analysis, Western Blot, Fluorescence quantitative (qPCR), High-Throughput Sequencing, etc.
CUSABIO Exosome isolation kit provides a simple and reliable method to extract intact exosomes from the cell culture supernatant, serum, plasma, latex, urine, saliva.

b. Choose serum-free media for cell culture.
c. Choose exosome-free serum for cell culture.
WB validation of specific markers, transmission electron microscope (TEM), particle size (NanoFCM, NTA), etc.
a. Simple, stable and highly repeatable.
b. No equipment requirement.
Why Study Exosomes?
Extracellular vesicles (EVs) are small membrane vesicles, composed of a lipid bilayer with inserted transmembrane proteins, enclosing cytosolic components (protein, mRNA, and miRNA) derived from the EV-producing cells.
These EVs such as exosomes have been found in biofluids, including blood, saliva, urine, cerebrospinal fluid (CSF) and latex, act as messengers of intercellular communication networks. EVs carry lipids, proteins, and RNAs derived from their producing cells, and have potential as biomarkers specific to cell types and even cell states.

How Do You Get Exosomes?
However, conventional methods (such as ultracentrifugation or polymeric precipitation) for isolating EVs have disadvantages regarding purity and feasibility. You can click here to get the comparision of five exosome isolation methods.
An exosome isolation kit can solve all your problems on exosome isolation. It is also the reason why CUSABIO keeps invest in developing high quality exosome isolation kits for so many years.
