  • Publication number: 20220074929
    Abstract: Methods of quantification, isolation, and characterization of exosomes are provided. Exosomes can be quantified by contacting a sample with a capture bead comprising a bead and a first binding agent, and a second binding agent. The first binding agent binds to a first biomolecule in the exosomes to produce a first complex and the second binding agent binds to a second biomolecule in the exosomes of the first complex to produce a second complex. The first complexes and the second complexes are quantified based on a detectable signal conjugated to the second binding agent. A microwell or a droplet generation is utilized to quantify the first complexes and the second complexes. Quantifying the exosomes is used to diagnose a cancer in a subject. In such methods, the first and the second binding agents bind to cancer biomarkers present in the exosomes.
