ELISAs showing humoral immune responses of mice immunized with D1NS1-HEK and D4NS1-HEK cells. a and b: Mouse antisera of D1NS1-HEK (red, panel a) and D4NS1-HEK (blue, panel b) immunized mouse groups (4 mice each) were analyzed on recombinant D1NS1 and recombinant D4NS1, respectively. c and d: Serotype cross-reactive humoral immune responses of D1NS1-HEK (red, panel c) and D4NS1-HEK (blue, panel d) mouse groups were analyzed on recombinant D4NS1 and recombinant D1NS1, respectively. Blue line (panel c) and red line (panel d) = pool of D4NS1-HEK and D1NS1-HEK mouse antisera, respectively, to enable direct comparison with the level of serotype-specific immune responses. e and f: Analysis of pooled mouse sera (red = D1NS1-HEK (e), blue = D4NS1-HEK (f)) on an unrelated hexa-His tagged protein (MUL_3720) as a control for humoral responses against the hexa-His tag. Black line in all panels = pool of mouse sera before immunization (pre-bleed)

| Recombinant dengue virus type 4 NS1 antigen is a purified preparation of the dengue virus serotype 4 (DENV4), non-structural protein 1 (NS1). DENV4 is one of four (DENV1-4) antigenically distinct, closely related viral serotypes belonging to the Flaviviridae family, genus flavivirus. All four serotypes are known to cause viral infection in humans. Dengue virus is common mosquito-borne infection and a major cause of morbidity in tropical and subtropical regions. There is currently no vaccine to prevent, or effective anti-viral drugs to treat, dengue virus infection. In many cases infection is assymptomatic and the majority of individuals who get ill only suffer the mild, non-specific febrile symptoms characteristic of dengue fever (DF). Only a minority of infections result in severe disease, manifesting as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Dengue virus infection gives lifelong immunity to the serotype in question but subsequent infection with another serotype may increase the likelihood of severe disease. The NS1 glycoprotein is essential for viral replication and viability, and since this protein is secreted into the bloodstream, tests have been developed to diagnose DENV infections using NS1, including antigen-capture ELISA, lateral flow antigen detection, and the measurement of NS1-specific IgM and IgG responses (Guzman, M.G. et al. 2010). Recombinant DENV4 NS1 antigen is presented in its native folded state complete with post-translational modifications, delivering optimal antigenicity and making it suitable for use in vaccine research and serology-based assays. |
