Quantification of Histidine-Rich Protein 3 of Plasmodium falciparum.

Quantification of Histidine-Rich Protein 3 of Plasmodium falciparum. Monoclon Antib Immunodiagn Immunother. 2018 Apr 10;: Authors: Palani B Abstract Malaria is a life-threatening infectious disease and continues to be a major public health crisis in many parts of the tropical world. Plasmodium falciparum is responsible for the majority of mortality and morbidity associated with malaria. During the intraerythrocytic cycle, P. falciparum releases three proteins with high histidine content as follows: histidine-rich protein 1 (HRP1), histidine-rich protein 2 (HRP2), and histidine-rich protein 3 (HRP3). Currently, most of the diagnostic tests of P. falciparum infection target HRP2, and a number of monoclonal antibodies (mAbs) against HRP2 have been developed for use in HRP2 detection and quantification. When parasites have HRP2 deletions, the detection of HRP3 could augment the sensitivity of the detection system. The combination of both HRP2 and HRP3 mAbs in the detection system will enhance the test sensitivity. In the HRP quantitative enzyme-linked immunosorbent assay (ELISA), both HRP2 and HRP3 contribute to the result, but the relative contribution of HRP2 and HRP3 was unable to investigate, because of the nonavailability of HRP3 specific antibody ELISA. Hence an ELISA test system based on HRP3 is also essential for detection and quantification. There is not much documented in the literature on HRP3 antigen and HRP3 specific mAbs an...
