Fig 8. Detection of the EV71 VP1 antigen by NLFOA.

Fig 8

The EV71 VP1 antigen was spiked in sera and anzlysed in parallel by NLFOA (A) and the conventional ELISA (B). The dotted line indicates the cutoff value that is 2.1-fold of that of the negative control (NC). Each assay was performed in three independent experiments. Means ± SD are shown.
