Dengue virus NS1 protein plays an important role in viral replication in the host cell and it is detected in high level in the infected patient serum. A synthetic gene of untagged DENV-2 NS1 with codons optimization for expression in Escherichia coli has been generated and then inserted into an expression vector pET16b. As a hydrophobic protein with aliphatic index of 71.21%, DENV-2 NS1 was produced as inclusion bodies in E. coli BL21(DE3). The DENV-2 NS1 aggregate was unfolded in 8 M urea and then refolded by reverse dilution method. The refolded DENV-2 NS1 has immunologically active structure as it is capable to interact with anti-NS1 antibody, hence making it as a potential vaccine candidate.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Expression in Escherichia coli,Expression vectors,Hydrophobic protein,Infectious disease,Non-structural,Refolding,Serotypes,Subtropical regions[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Dengue virus serotype 2,Escherichia coli,Non structural protein 1,Refolding,Vaccine candidate[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]We thank Program Pengembangan Teknologi Industri (PPTI) 2016, Indonesia Ministry of Research, Technology and Higher Education for funding this work.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.3844/ajbbsp.2018.230.237[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
