Detection limit of RH antigen according time and temperature. The ELAA assays were performed with AP001 (A,C) and AP002 (B,D) anti-ROP18 aptamers. We evaluated incubation 1 h at 37°C (A,B) and 4°C overnight (C,D). Different concentrations of T. gondii total antigen of the RH strain (RH Ag) were evaluated and three negative controls, PDI, LucGT, and BSA were included. The data are represented with the mean of each sample evaluated in triplicate. Welch's t-test. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 vs. controls without antigen (No Ag).
