DENV2 (strain Thailand/16681/1984) NS1 protein, His Tag (MALS verified)

  • Synonym
    NS1
  • Source
    DENV2 (strain Thailand/16681/1984) NS1 protein, His Tag(NS1-D52H3) is expressed from human 293 cells (HEK293). It contains AA Asp 776 - Ala 1127 (Accession # P29990-1 ).
    Predicted N-terminus: Asp 776
  • Molecular Characterization
    NS1 Structure

    This protein carries a polyhistidine tag at the C-terminus

    The protein has a calculated MW of 41.8 kDa. The protein migrates as 45-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

The purity of DENV2 (strain Thailand/16681/1984) NS1 protein, His Tag (Cat. No. NS1-D52H3) is more than 90% and the molecular weight of this protein is around 200-225 kDa verified by SEC-MALS.

Bioactivity-ELISA
 NS1 ELISA

Immobilized DENV2 (strain Thailand/16681/1984) NS1 protein, His Tag (Cat. No. NS1-D52H3) at 1 μg/mL (100 μL/well) can bind Mouse Anti-NS1(DENV) Antibody 2B7,Mouse IgG1 with a linear range of 0.1-2 ng/mL (QC tested).

  • Background
    Dengue is a mosquito-borne viral disease widely spread all over the world transmitted by 4 serotypes of dengue virus (DENV). The symptoms range from mild dengue fever to dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) with high mortality. Currently, most of the studies on DENV vaccines emphasize on its envelope protein (i.e., Sanofi’s tetravalent dengue vaccine Dengvaxia). However, the fact pointing out that the vaccines with Envelope protein may could have negative effect on people never infected by DENV which makes the non-structural protein NS1 become another great target for vaccine research with its ability to avoid Antibody Dependent Enhancement.
