ABSTRACT
OBJECTIVE:
To clone a gametocyte specific protein Pfgdv1 of Plasmodium falciparum, express and identify recombinant Pfgdvl protein in vitro.METHODS:
PCR was performed to amplify Pfgdv1 from P. falciparum DNA which was got from the patient who was infected with P. falciparum, and the PCR product was inserted into pET28a (+) vector. pET28a-Pfgdv1 recombinant plasmid was constructed and transformed into E. coli host BL21 (DE3+). IPTG was used to induce the recombinant Pfgdv1 protein fused with His tag, and the protein was purified by His-NTA affinity chromatography. The recombinant protein was identified by SDS-PAGE and Western blotting.RESULTS:
The PCR product of Pfgdv1 gene was about 1.65 kb, meeting the expectation of predicted fragment size. The recombinant protein was about 67 kDa, which could be recognized by His-Tag monoclonal antibody.CONCLUSION:
The Pfgdv1 gene of P. falciparum is successfully cloned, and the recombinant Pfgdv1 protein is expressed, thereby providing an opportunity for further study on transmission blocking vaccine.
