Figure 1: Exosome quantification scheme.
(A) Schematic of multi-well protein A/G slides (192 wells) used in this assay. (B) Target exosomes are directly captured from samples, including serum and plasma, by surface immobilization on the capture antibody (e.g. anti-EphA2 antibody) bound to the slide, and then incubated with gold nanorods conjugated with a detection antibody (e.g. anti-CD9 antibody) before analysis by DFM image analysis.
