Figure 2. Selection of antibody pairs for the multiplex detection using a microsphere immunoassay.

Figure 2

The detection of (A) Acidovorax avenae subsp. citrulli (Aac) and (B) no antigen using eight antibodies-coated microsphere and R-Phycoerythrin (RPE) labeled antibodies, including 11E5 antibody. The detection of (C) Aac, (D) chilli vein-banding mottle virus (CVbMV), (E) watermelon silver mottle virus (WSMoV), (F) melon yellow spot virus (MYSV) detection and (G) no antigen with seven antibodies- coated microsphere and RPE-labeled antibodies without using 11E5 antibody. X-axis is antibody-coated microsphere and y-axis is median fluorescent intensity (MFI) from each RPE-labeled antibody. (H) Summary of selected antibody pair sets for the detection of the four plant pathogens.
