Left column: Immuno-fluorescence staining using anti-HDP antibodies showed that transfected parasites continually expressed HDP (green). Arrows on the DIC image indicate hemozoin. Parasite nucleus (blue) is stained with DAPI. Right column: Non-specific recombination of HDP-YFP chimera. Immuno-fluorescence staining of with anti HDP antibodies also indicated the expression of the native HDP. Arrows on the DIC image indicate hemozoin. Parasite nucleus (blue) is stained with DAPI.
