Additional file 2. Evaluation of the rVP3 ELISA. (A) rVP3 ELISA A/P values of samples considered negative (left) and positive (right) by the commercial test. The horizontal line represents the cut-off 0.0496. (B) Correlation (R2=0.24) between commercial ELISA (y-axis) and rVP3 ELISA (x-axis) O.D. values. A/P = sample O.D. mean – negative control O.D. mean/ positive control O.D. mean – negative control O.D. mean.
