Dengue Virus (DENV-Env Serotype 4) Ag ≥95%

The recombinant envelope (Env) ectodomain antigen from Dengue virus serotype 4 is supplied by Antibodies.com as an affinity-purified protein at ≥95% purity by SDS-PAGE. This DENV-4 Env ectodomain reagent is intended for use as an immunogen in vaccine research and as a coating reagent in ELISA-based serology assays that distinguish serotype-specific antibody responses. Researchers studying flavivirus immunity, dengue epidemiology, and pan-serotype diagnostic panels use DENV serotype antigens to characterize convalescent sera, monoclonal antibody binding, and epitope mapping studies. The product is supplied as 100 µg of lyophilized recombinant antigen suitable for reconstitution in working buffers, and supports downstream applications including Western blot, immunoprecipitation, and flow cytometry in addition to ELISA. Recommended storage is at -20 °C or below for long-term stability; avoid repeated freeze-thaw cycles by aliquoting after reconstitution. For research use only; not intended for diagnostic or therapeutic procedures.
