Exosomes play an important role in intercellular signal transduction and are a novel source of biomarkers for diagnosis and prognosis of diseases. Recently, there is evidence that cytokines are released from encapsulated exosomes, and once in contact with sensitive cells, they can cause biological effects. For exosomal cytokine detection, Creative Biolabs provide a comprehensive service, and provide a very flexible and professional choice for each specific project requirements.

Background of Exosomal Cytokines

The bidirectional communication between cells and their microenvironment is essential for maintaining the human body under physiological and pathological conditions. Cytokines are important regulators of immune function and inflammation, and are susceptible to many factors, which may lead to the high degree of heterogeneity observed in the study. In multicellular organisms, they are generally considered to be soluble factors that mediate cell-to-cell communication. Their secretion can be carried out in a typical secretion mode or through exosomes.

Relationship of Exosome and Cytokines

A growing body of evidence shows that exosomes are one of the main players in cell-to-cell communication and drive inflammation, autoimmunity, and infectious disease pathology. They can be a source of pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-6, -1β, -8 (IL-6, IL-1β, IL-8), monocyte chemoattractant protein-1 (MCP-1) can stimulate a variety of cells to produce them. It can also induce the activation and proliferation of B cells and T cells, as well as the migration of granulocytes to inflammatory tissues, and promote the inflammatory pathway of recipient cells. These studies indicate that exosomal-related cytokines (exosomal cytokines) may be novel biomarkers.

Exosomal Cytokines Profiling Service

At present, we provide multi-parameter analysis of exosomal cytokines to provide research assistance for scientific researchers. Our platform advantages are as follows:

1. Many groups of cytokines can be detected at one time, and the required amount of samples is small. It only needs 25 μl to detect multiple indicators;
2. The cost of reagent is saved and the cost is more economical than ELISA;
3. High sensitivity, wider dynamic range than fluorescence colorimetric method;
4. Better reproducibility, less sample operation with approximately the same liquid kinetics.
