(A) Sensorgrams recorded for the interactions of anti-CD9 (black line), anti-CD63 (green line), and anti-CD81 (red line) interactions with EVs derived from the A549 cell culture medium. (B) Calibration plots. Experimental conditions: 0.01 M PBS-Gibco (pH 7.4; 0.005% Tween), CAbs = 1.0 μg·mL–1, and CEVs: 6.1 × 104 to 6.1 × 107 particles·mL–1.
