Figure 5. Direct detection of parasites in a sandwich ELISA.

Figure 5

Antibody A10 was immobilized on the surface of microplate and then parasites was added. After washing, Fab-H3 displayed phage was added and A10, parasite, phage-H3 form a complex, and immobilized on the surface by A10. HRP/anti-M13 monoclonal antibody conjugate was used to detect the complex. (A) Schematic diagram for detection of parasites. (B) Correlation between parasite and Fabs with a correlation factor of 0.9902 (n = 3). Bovine serum albumin (BSA) was used as a negative control.
