aDP: Double positive staining by both anti-IgG antibody and OVA. bSP: Single positive staining by anti-IgG antibody and negative staining by OVA. “+” means antibody binds native OVA, while “-” means a
a The titers of supernatants were defined as the reciprocal of the dilution that gave an absorbance closest to 1.0. b ZEA was prepared by diluting the standard solution with PBS, mixed with equivalent
aThe titer was defined as the reciprocal of the dilution that gave an absorbance most close to 1.0. bSTG was prepared by diluting the stock solution with 10% methanol-PBS to 200 ng mL−1 and mixed with
