Bending signal example. (Left) An example of a bending signal from cantilever A, B, C, D normalized to zero at t = 0 under the addition of BAM antibody; (Right) The differential values of A (signal) - B(reference), C(reference) - D(signal), B(signal) - C(signal), and A(reference) - D(reference) . The antibody is added at t = 200 and enters the cantilever chamber at t = 500, gradually causing a lasting differential signal of approximately 0.02 mV for the specific antibody.
