ELISA is a sandwich ELISA assay for quantification and characterization of exosomes in cell culture supernatant and biological fluids. The non-invasive protein biomarkers of exosome can be used for detection and monitoring of a number of pathological conditions. Creative Biolabs has successfully launched an innovative exosome characterization platform based on ELISA.

Enzyme-linked Immunosorbent Assay (ELISA)

Enzyme-linked immunosorbent assay (ELISA) is both widely used as diagnostic tools in medicine and as quality control measures in various industries;it is also used as analytical tools in biomedical research for the detection and quantification of specific antigens or antibodies in a given sample. ELISA uses the basic immunology concept of an antigen binding to its specific antibody, which allows detection of very small quantities of antigens such as proteins, peptides, hormones, or antibody in a fluid sample. ELISA utilizes enzyme-labeled antigens and antibodies to detect the biological molecules, the most commonly used enzymes being alkaline phosphatase and glucose oxidase.

Exosome Characterization via ELISA

ELISA specifically capture exosomes by exosome specific protein antibodies from different biological samples, including cell culture supernatant and biological fluids. The quantification and characterization of exosomes proteins are followed by the use of appropriate detection antibodies to detect the exosomes associated antigens, which can be generic or cell-specific exosomes. Exosome can perform different biological functions due to its different proteins. For example, exosome secreted by tumor cells can mediate the proliferation and immune escape of angiogenic tumor cells. Dendritic cell-derived exosomes can elicit an effective anti-tumor immune response. Thus, the non-invasive protein biomarkers of exosome can be used for detection and monitoring of a number of pathological conditions.
