Dengue Virus (DENV-Env Serotype 3) Ag ≥95%

A recombinant ectodomain construct of the Dengue Virus Serotype 3 envelope glycoprotein, affinity purified to ≥95% purity and supplied at 100 µg per vial by Antibodies.com. The antigen is intended for ELISA plate coating and use as an immunogen, supporting serotype-specific assay development, seroprevalence studies, and flavivirus diagnostics research. Because dengue has four antigenically distinct serotypes (DENV-1 through DENV-4), researchers use DENV-3-specific antigens like this one to differentiate DENV-3 immune responses from those against other serotypes in surveillance panels and vaccine candidate screening. The ectodomain preserves the receptor-binding and fusion-relevant epitopes recognized by neutralizing antibodies, which is important for both functional immunoassays and immunization studies. Affinity purification and recombinant expression support lot-to-lot consistency, reproducible standard curves in quantitative ELISA formats, and consistent presentation of conformational B-cell epitopes. Handle as a frozen protein to preserve activity across freeze-thaw cycles. For research use only.
