Abstract

Objectives: To study the cloning, expression, and purification of the general NS1 antigen with epitope-detectable antibodies against four Dengue virus (DENV) serotypes. Methods: The gene coding for NS1 antigen generally four serotypes was inserted into pET22b+ vector then transformed into E.coli BL21. Recombinant products were examined by PCR, restriction enzyme, sequencing, and SDS-PAGE methods. Results: The gene encoding the recombinant NS1 antigen with a size of 417 bp, 139 amino acids, and 100% homology with the polypeptide sequence of the NS1 antigen was published on GenBank. SDS-PAGE electrophoresis results showed that the recombinant protein 6xHis-rNS1 has a molecular weight of approximately 18 kDa. Conclusion: Successful expressed the recombinant NS1 antigen in E.coli. It was the initial result of research aimed at creating monoclonal antibodies to detect four serotype DENVs in Vietnam.
