FIG. 3. — Optical density values obtained by performing ELISA with several serum groups. Horizontal lines indicate the cutoff values calculated for each peptide. (A) Results obtained for each fragment when assaying Ch+ and Ch− control serum groups. Points in columns a and b show results for TcP2β_FL, points in columns c and d show results for TcP2β_N, and points in columns e and f show results for TRX. Points in columns a, c, and e correspond to results for Chagas' disease-positive sera; points in columns b, d, and f correspond to results for Chagas' disease-negative sera. (B) Results obtained for each fragment when assaying the AID serum group. Points in column a show results for TcP2β_FL, points in column b show results for TcP2β_N, and points in column c show results for TRX. (C) Results obtained for each fragment when assaying the L serum group. Points in column a show results for TcP2β_FL, points in column b show results for TcP2β_N, and points in column c show results for TRX.
