Exosome-Mediated Small Molecule Delivery Service

Exosomes are nanoscale extracellular vesicles, naturally released by various cell types, including cancer cells, stem cells, and immune cells. These vesicles are involved in intercellular communication by transferring bioactive molecules such as proteins, lipids, mRNA, and small molecules, playing key roles in multiple physiological and pathological processes. One of the most exciting applications of exosomes is their potential as carriers for small molecule delivery. Their biocompatibility, ability to cross biological barriers, and targeted delivery capabilities make exosomes ideal vehicles for the therapeutic and diagnostic transport of small molecules.

 

In recent years, exosome-mediated delivery has become a powerful tool for small molecule drug delivery, enabling enhanced cellular uptake, stability, and precise targeting. This approach has garnered considerable attention for its potential in overcoming the challenges of conventional drug delivery systems, such as poor solubility, instability, and off-target effects. Exosome-based delivery offers a promising strategy for increasing the bioavailability of small molecules and enhancing therapeutic efficacy.

Service at MtoZ Biolabs

MtoZ Biolabs offers Exosome-Mediated Small Molecule Delivery Service designed to optimize the use of exosomes as vehicles for targeted small molecule delivery. Our Exosome-Mediated Small Molecule Delivery Service utilizes advanced exosome isolation, cargo loading, and functionalization techniques. The service supports both basic and clinical research by providing high-quality, functionalized exosomes capable of efficiently delivering small molecule drugs, siRNAs, mRNAs, or other therapeutics directly to targeted cells or tissues.

 

Our service includes the following:

💠Exosome Isolation and Purification: We offer a range of isolation techniques, including ultracentrifugation, SEC, and immunoaffinity capture to ensure high-purity exosome preparations.

💠Exosome Characterization: Exosome quality and characterization are critical for ensuring the success of the delivery system. We utilize nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), and western blotting to confirm exosome size, integrity, and surface marker expression.

💠Small Molecule Loading: Our service includes the loading of small molecules such as chemotherapeutic agents, RNA therapies, and small molecules using state-of-the-art methods such as electroporation, sonication, or membrane fusion.

💠Exosome Functionalization: We modify exosome surfaces with ligands, peptides, or antibodies to enhance targeting specificity for desired tissues or cells. This is particularly useful for targeted therapies, including drug delivery to tumors or brain cells.

💠Therapeutic Validation: We conduct in vitro and in vivo functional assays to assess the efficacy and bioactivity of exosome-based delivery systems, including cell viability assays, migration assays, and drug sensitivity tests.
