It causes significant morbidity __ampersandsignamp; mortality worldwide, including countries with mainly imported malaria. Malaria parasite Plasmodium falciparum is the most common cause of severe __ampersandsignamp; life threatening malaria __ampersandsignamp; accounts over 1 million deaths every year. Microscopy of Giemsa-stained thick __ampersandsignamp; thin films remains the current gold standard for diagnosis. Although it has good sensitivity __ampersandsignamp; allows species diagnosis, it is time consuming, required equipments __ampersandsignamp; skilled personnel. Antigen tests based on antigen capture assay are capable of detecting fewer parasites and of producing the results more quickly. Such antigen which is shown promising results is plasmodium falciparum histidine rich protein-2 (PfHRP-2). HRP-2 is contained tendem repeats of the sequences AHH __ampersandsignamp; AHHAAD and has B-cells epitopes that allows its detection. In this study chemically HRP-2 antigen peptides were synthesized by solid phase technique __ampersandsignamp; purified by HPLC gel chromatography. Microsphere (PLGA __ampersandsignamp;PVA) entrapped peptides are injected to mice __ampersandsignamp; rabbits subsequent booster doses. The high titre/affinity antibodies raised against these peptide antigens were estimated by indirect ELISA technique. The peptide specific peak absorbance varied from 0.6 to 2.6. The variation in the titre of antibody generated in mice __ampersandsignamp; rabbits depend upon the individual immune responsive capacity. Incremental increase in antibody titre with microscope delivery may result in sustained release of the antigen. Our studies show that chemically synthesized peptides of PfHRP-2 delivered in microsphere were able to generate immune response that can be quantified. This paves for development of tools for early diagnosis of malaria.&#13;
