Abstract
A lateral flow assay device includes several test strips to receive a quantity of fluid that includes a quantity of exosomes and detect the presence of a target analyte on the surface of the exosomes. Each test strip includes a conjugate pad that contains binding reagent to one type of tetraspanin protein conjugated with a label. Each type of tetraspanin binding reagent is configured to bind with a corresponding type of exosome tetraspanin and form an immunocomplex comprising an exosome. Each conjugate pad is fluidly connected to a corresponding membrane. Each membrane includes a test line that includes an immobilized binding reagent to the target analyte. The immobilized binding reagent to the target analyte is configured to bind to a protein of the target analyte on the surface of an exosome in an immunocomplex comprising the exosome.
