Dengue Virus (DENV-Serotype 4) Ag

This serotype 4 dengue virus antigen preparation from Antibodies.com is supplied in a liquid formulation as 1ml per vial, ready for direct use in ELISA workflows and related immunoassay development. Dengue virus is a mosquito-borne flavivirus transmitted primarily by Aedes aegypti and Aedes albopictus, and it is responsible for dengue fever, dengue hemorrhagic fever, and dengue shock syndrome across tropical and subtropical regions worldwide. Among the four antigenically distinct serotypes (DENV-1 through DENV-4), serotype-specific reagents are essential tools for differentiating past exposures, monitoring circulating strains, and supporting vaccine candidate evaluation.

As a research-use reagent, this antigen supports seroprevalence studies, immune response profiling, and the development of diagnostic assays that require serotype-level resolution rather than pan-flavivirus detection. The liquid format simplifies dilution and coating onto microplates, enabling reproducible antigen presentation across experimental batches. Laboratories working on flavivirus immunology, vector-borne disease surveillance, and recombinant antigen design can incorporate this material into controlled in vitro studies of viral antigenicity and immunogenicity, including investigations of antibody-dependent enhancement relevant to secondary heterotypic infection.
