From: The C-terminal region of Trypanosoma cruzi MASPs is antigenic and secreted via exovesicles
ELISA of peptides C1–C7 and parasite lysates (total antigen) using sera from patients infected with T. cruzi with different manifestations of the disease (gastrointestinal (a), cardiopathic (b) and asymptomatic (c)). All the samples with values for OD 492 nm sample/cut-off above 1 were considered positive. The cut-off value was calculated using a pool of negative sera from Panama with the following formula: Mean + 3 × SD pool of negative samples.
