Exosome Isolation and Purification

Exosomes are small extracellular vesicles and present in almost all types of body fluids. They can be loaded with various materials such as proteins, RNAs and DNA, therefore they are crucial for cell-cell communication by transmitting signals to regulate diverse cellular functions in recipient cells present at particular sites. They can also exert a significant impact on the development of disease processes. Recently, exosomes are becoming a hot topic for research, especially in the fields of disease diagnosis, prognosis, therapy, and biomarker discovery. The isolation and purification of exosomes from biological fluids is a prerequisite step in exosome research. High purity of exosomes is still technically challenging to achieve which can affect the outcome.

Different biophysical and biochemical properties can be adapted to isolate exosomes, including size, mass density, shape, charge, and antigen exposure. The principles of the most common isolation methods are presented below.

Creative Bioarray provides reliable techniques for exosome isolation from different sample matrices. We also provide exosome isolation using specified techniques if required by customers. We will perform QC assays to ensure the integrity and purity of the isolated materials.

Creative Bioarray provides exosome isolation and purification services, including but not limited to:
