Fig. 3. The lowest concentrations of rCatB3 and CatB3 in WB of newly excysted
juveniles (NEJ) and metacercariae (Met) of F. gigantica as detected by the sandwich
ELISA assay. Lines with black circle, white triangle and black square indicate the
concentration levels of rCatB3 and catB3 in WB of NEJ and Met of F. gigantica antigens,
and arrows indicate the lowest concentrations that CatB3 could still be detected in
each sample.
