Fig. 2From: Monoclonal antibody-based colloid gold immunochromatographic strip for the rapid detection of Tomato zonate spot tospovirusTiter of three mAbs 3A2, 5D2, 5F7 in the detection of Tomato zonate spot virus using the indirect ELISA. The experimental samples were used as positive (P) control, which extracted from three TZSV-infected N. benthamian leaves, and using healthy N. benthamian leaf extracts as negative (N) control. The P/N value of more than 2 indicated the positive result, and those of less than 2 represented the negative result. The X axis shows the dilution factor of mAbs 3A2, 5D2, 5F7 for TZSV and the Y axis the OD450 value for P/NBack to article page
