SPR sensograms correspond to the injection of 10-fold diluted sera into an array-format SPR sensor. (a) SPR results from TB patient sera and (b) SPR results from normal control sera. All experiments were carried out at room temperature in triplicate, and a flow rate of 30 μL/min was used. Results shown were averages of three independent experiments.
