Fig 4. Mean fluorescence intensity obtained from labeling of epimastigote forms of the two T. cruzi clonal populations.

Col1.7G2 (blue) and JG (red) with polyclonal antibodies against different T. cruzi anti—oxidant enzymes: Ascorbate peroxidase, APX; Mitochondrial Peroxiredoxin, MPX; Superoxide Dismutase A, SOD A; Superoxide Dismutase B, SOD B; Trypanothione Redutase, TR and Trypanothione Synthase, TS before (A) and after (B) treatment with 30 μM H₂O₂. Dotted lines represent control non-labeled parasites.
