Exosome extraction is a specialized technical process aimed at isolating nanoscale vesicles (30-150 nm) from biological fluids such as blood, urine, or cell culture media. Throughmethods such as ultracentrifugation, chromatography separation, and immunoaffinitypurification, exosomes carrying important biomolecules like proteins and nucleic acids areprecisely obtained. These exosomes are then identified and quality-controlled usingtechniques such as transmission electron microscopy for nanoparticle tracking and Westernblotting. This technology provides essential material support for the discovery of diseasediagnostic biomarkers, the development of targeted drugs, and the study of cell communication mechanisms.
