Background: Immediate and accurate diagnosis of malaria is essential for effective control of this disease. Immunochromatographic based rapid diagnostic tests (RDTs) are economical, simple to perform, and provide results in a relative short time, can be useful to assist effective management of malaria. The commercially available malaria RDT in Indonesia is still imported. Therefore, an effort to produce malaria RDT independently is necessary. One of the biomarkers used in RDTs is Plasmodium lactate dehydrogenase pLDH. The production and accumulation of pLDH during asexual stage or blood-stage in all human infected malaria parasites can be used to indicate parasites viability, which is correlated with the number of parasites present in the plasma of infected patients. Objective: The aim of this research is to produce recombinant PfLDH in Escherichia coli BL21(DE3).Methods: PfLDH gene was cloned into pET30a expression vector to obtain a 6.2 kbp recombinant plasmid pET30a-PfLDH. E. coli BL21(DE3) was transformed with pET30a-PfLDH using the heat shock method. Then, E. coli BL21(DE3)- pET30a-PfLDH was cultured in LB broth containing 50 mg/mL kanamycin and was induced by 1mM IPTG at 37oC.Results: SDS-PAGE and Western Blot analysis showed that recombinant PfLDH was expressed with molecular mass ~30 kDa.Conclusion: Recombinant PfLDH is expressed in E. coli BL21(DE3) and can be used in further research for producing rPfLDH as a biomarker for malaria RDT development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
