Exosomes are present in biological and cell culture fluids but often mixed with cell debris and protein aggregates. Compared to nucleic acids, detecting differential expression of exosome proteins is challenging due to contamination risks with conventional isolation methods. Creative Biostructure can isolate and purify high-purity exosomes for biological analysis.

Creative Biostructure provides various methods for exosome isolation, including traditional differential centrifugation, density gradient centrifugation, and more recent methods such as ultrafiltration, polymer precipitation, immune separation, isolation screening, and size exclusion chromatography.
