Evaluation of a monoclonal antibody affinity purified antigen for zymodeme specific serological diagnosis of Trypanosoma cruzi infection
Theoretically, serological assays with affinity purified marker antigens can allow strain-specific diagnosis even when parasites cannot be retrieved from and infected host. A Trypanosoma cruzi antigen was purified by affinity chromatography using a zymodeme (Z) 2 specific monoclonal antibody (2E2C11...
