(A) Immunoreaction dynamics of FIT/FIC at
different AFB1 concentrations. (B) Effect of pH value of
samples on FIT, FIC, and FIT/FIC ratio. Competitive inhibition rate was defined as (1 – B/B0) × 100%, where B0 and B represent FIT/FIC of the negative sample and an AFB1 spiked
sample solution (10 pg mL–1), respectively. (C)
Optimized standard inhibition curve for AFB1 was obtained
by plotting the normalized signal B/B0 × 100% against the logarithm of AFB1 concentration. Data were obtained by averaging three independent
experiments. (D) Effect of methanol in samples on FIT,
FIC, and FIT/FIC ratio.
