Bacterial Extracellular Vesicle Services
To harness the full potential of bacterial extracellular vesicles (BEVs) for advanced therapeutic and diagnostic applications, it is crucial to have reliable methods for their extraction, purification, characterization, and analysis. Creative Biostructure offers comprehensive BEV services to meet these needs, enabling precise and efficient utilization of BEVs in cutting-edge biomedical research.
What Are Bacterial Extracellular Vesicles (BEVs)?
BEVs are nanosized vesicles derived from bacteria that play a crucial role in intercellular communication by transferring bioactive molecules to recipient cells. They are characterized by their lipid bilayer composition and can carry a variety of cargo, including proteins, nucleic acids, lipids, and metabolites. BEVs are comparable to liposomes and have emerged as a novel platform for drug delivery due to their biocompatibility and ability to encapsulate and transport various bioactive molecules.

A, et al., 2023).
Advantages Over Traditional Drug Delivery Systems
- Cost-Effective Production: Bacteria's rapid proliferation makes BEV production more efficient and less costly compared to traditional drug delivery systems.
- Precision and Customization: Modern gene editing tools allow for the precise manipulation of BEV composition and functionality. This facilitates the development of targeted treatments tailored to specific diseases.
- High-Density Culture Technology: Advances in culture technology enable mass production of BEVs. This industrial scalability ensures a steady supply of vesicles for clinical applications.
- Synthetic Biology Applications: Synthetic biology opens new avenues for creating multifunctional and customized BEVs. By designing and modifying bacteria, scientists can generate BEVs with specific properties aimed at particular diseases. These engineered BEVs can transport therapeutic drugs, immunomodulatory molecules, or diagnostic markers with high precision, improving the effectiveness of disease treatment.

Bacterial Extracellular Vesicle Extraction
Our extraction services employ a range of state-of-the-art techniques to isolate BEVs effectively. Utilizing methods such as PEG precipitation, which aids in the concentration of vesicles, ultracentrifugation for high-speed separation, magnetic bead extraction for targeted isolation, and density gradient centrifugation to purify based on density differences, we ensure the recovery of high-quality BEVs. These methods are meticulously chosen to suit various research requirements and sample types, providing a robust foundation for downstream applications.
Bacterial Extracellular Vesicle Purification
Purification is a critical step following extraction, and we achieve this through a meticulous process. Initially, low-speed centrifugation removes bacteria and debris from the fermentation broth. This is followed by sterile filtration to eliminate any residual bacteria and proteins unrelated to BEVs. Our purification protocols are designed to obtain BEVs of the highest purity, ensuring that subsequent analyses and applications are not confounded by contaminants.
Bacterial Extracellular Vesicle Characterization
Characterization of BEVs is essential to understand their properties and behavior. We offer a suite of characterization services, including transmission electron microscopy (TEM) imaging for morphological assessment, nanoparticle tracking analysis (NTA) for size distribution and concentration measurements, Western Blot for protein profiling, and flow cytometry for surface marker analysis. Additionally, we provide exosome quantitative analysis to determine the yield and purity of the BEV preparation, ensuring that our clients have a thorough understanding of their samples.
Bacterial Extracellular Vesicle Microbiomics Analysis
Recognizing BEVs as crucial communicators in the intricate dialogue between intestinal microorganisms and host cells, our microbiomics analysis service is pivotal. We have established an advanced platform that leverages cutting-edge sequencing technologies and bioinformatics tools to dissect the microbial composition associated with BEVs. This analysis is vital for understanding the role of BEVs in gut microbiome-host interactions and their potential implications in health and disease. Our microbiomics analysis provides insights into the functional potential of the microbiota encapsulated within BEVs, paving the way for targeted therapeutic strategies.
