Sensitivity of dual LFIA for simultaneous detection of S. Enteritidis and E. coli O157:H7. Left: dual LFIAs without TMB solution. Right: dual LFIAs with TMB solution. (A, D) Typical photo image of dual LFIAs with different bacterial concentrations ranging from 0 to 108 cfu/mL. (B, E) Quantitative detections were performed by plotting the peak of two test lines (S and E). (C, F) Calibration curves of peak areas of test lines vs target concentrations. Error bars indicate standard deviations of the three measurements.
