Fig. 2From: A new immunochromatographic assay for on-site detection of porcine epidemic diarrhea virus based on monoclonal antibodies prepared by using cell surface fluorescence immunosorbent assayThe simple schematic diagram of the new ICA. a. The stereoscopic structure of the new ICA; b. Negative reaction. When negative spiked samples were added to the sample pad, no red line on the T-line was observed; c. Positive reaction. When positive spiked samples were applied to the sample pad, a red line was visible on the T-lineBack to article page
