With years of experience in the field of exosomes, Creative Biolabs has solved the problem of isolation and purification of exosomes from large-volume cell culture supernatant through concentration column and size exclusion chromatography (SEC), which are suitable for the requirements of industrial production of exosomes. In addition to the scalable upstream production of exosomes, we also provide downstream processing for efficient purification and characterization, to obtain high-quality, functional exosomes that are ready to use.

Introduction of Exosome Manufacturing

The manufacturing of exosomes first requires their secretion from appropriate cell lines such as stem cells and HEK 293 cells. Then, exosomes are isolated from the conditioned medium and separated from process-related contaminants including other extracellular vesicles, proteins, and cells. Thereafter, the harvested exosomes can be characterized by different techniques to ensure the quality and quantity of the final products.

Our Services

Creative Biolabs provides one-stop exosome large-scale production service. The process is divided into several key steps as follows:

Upstream cell line production methods. Fig.1 Upstream cell line production methods. (Colao, 2018)

  • Upstream Production - Cell lines (e.g., MSCs, ESCs) are cultured for exosome production with T-flasks. It takes several rounds of splitting and culture expansion to yield a large number of cells for exosome production. Often, the serum-free medium can be used to reduce contamination and to help exosome purification.
  • Exosome Purification - Exosomes can be purified using a variety of methods after cell harvest. To enable the production of scalable and pure exosome products, the most suitable approach and strategy will be adopted based on the starting volume and the intended downstream application of exosomes.
  • Exosome Analysis - In order to get a clear picture of the quality of your exosomes, we provide comprehensive characterization and quantification services. These include Nanoparticle Tracking Analysis (NTA), exosomal surface marker analysis (using FACS, WB, ELISA), physical observations (Mass spectrometry), and Tunable Resistive Pulse Sensing (TRPS). Besides, we can perform profiling services of the exosome cargo including RNA, proteins, and cfDNA.
  • Lyophilized Exosome - we can also freeze-dried the isolated exosomes to facilitate storage and transport.
