Due to their native structural property and function in cell-cell communication, exosomes have the potential to be used as a carrier of gene and drug delivery for disease treatment. As a professional research organization and years of experienced supplier in biotech markets, Creative Biolabs is devoted to offering high-level and cost-efficient customized exosome services for further understanding of exosome structure and biogenesis. Aided by our exosome engineering platforms and accurate results, researchers can rapidly and extensively refresh molecular mechanisms of exosome functions and expand insights into their practical potency.
Exosomes are considered to be a new generation of drug delivery platforms due to their high delivery efficiency, low immunogenicity, good biocompatibility, and easy crossing of the blood-brain barrier. Natural exosomes have poor targeting and are easily cleared by the body's immune system. Due to the characteristics and biogenesis of exosomes that make them easy to modify, it is necessary to add specific surface molecules (such as molecules targeting specific tissues or anti-phagocytic proteins) on the basis of their own lipid bilayer structure for engineering. This can improve the targeting and retention time of exosomes in the body. Both therapeutic molecules and molecules with specific functions can be modified in the lumen or surface of exosomes by different methods.
Currently, many studies have reported the application of engineered exosomes as therapeutic drugs in the treatment of various diseases. These data suggest that exosomes have great therapeutic potential in the future and are expected to be translated into clinical practice.

Creative Biolabs provides a range of customized exosome engineering services. For example, performing fluorescent or biotin-labeled exosomes to drive detection of their uptake by cells, biodistribution, and tumor enrichment patterns. We can construct well-targeted designed exosomes for the active targeting of exosomal cargoes to a variety of organs, cells, and disorders along with developing proven strategies for loading desired cargoes into exosomes. We are also committed to providing services based on engineering modifications to explore the exosomal anti-phagocytic and enhance their circulation behaviors. Notably, we combine the advantages of multispecific antibodies with exosome vehicles, designing exosomes modified with multiple antibodies, which carry multiple sites of interaction with targets. This confers stronger targeted delivery effects to exosomes and produces more significant anti-tumor cytotoxicity by redirecting immune effector cells. In addition, we offer production services for exosome-associated AAV vectors to enhance gene delivery. Creative Biolabs has designed several specialty exosome engineering services, including but not limited to:
Creative Biolabs is a technical service provider dedicated to the development and clinical transformation of exosomes. In terms of exosome modification, our professional technical team can provide the most comprehensive engineering exosome construction services, including pre-service consultation and all technical services from exosome isolation and identification to in vivo functional research and in vitro functional research. Furthermore, a better understanding of exosome components and their activity patterns is necessary before utilizing exosome engineering to develop therapeutic drugs. Therefore, we can also provide customers with systematic exosome analysis technology to comprehensively understand the content of exosomal protein, lipid, and exosomal RNA molecules in exosomes through high-throughput multi-omics solutions to design effective exosome-based drug carriers.
