Figure 3From: Production and characterization of specific monoclonal antibodies binding the Plasmodium falciparum diagnostic biomarker, histidine-rich protein 2Titration of mAbs D2, F9, and C1-13 against 0.1 μg rPfHRP2 protein. The antibodies were prepared in two-fold serial dilution, from 20 ng/mL in ELISA assay. 1% BSA protein was used as a negative control. The dotted line represents cut-off OD absorbance at 0.5.Back to article page
