Where to Buy Recombinant Dengue NS1 Antigens for Research

Researchers can request recombinant Dengue NS1 antigens from Beta LifeScience for ELISA development, antibody screening, immunogen studies, Western blotting and other laboratory applications. Available NS1 options represent DENV-1, DENV-2, DENV-3 and DENV-4 and include proteins expressed in E. coli, insect cells and HEK293 mammalian cells. The right product depends on the target serotype, amino-acid sequence, expression host, protein tag, purity, formulation and intended application. Start with the Beta LifeScience Dengue collection, which currently lists 42 recombinant Dengue products. Individual products are available through an online inquiry and quotation process rather than a standard direct checkout.

Which Dengue NS1 Antigen Should You Request?

The appropriate antigen is the product that most closely matches the biological target and assay design. Buyers should prioritize five factors.

1. Select the required Dengue serotype

Dengue virus has four antigenically distinct serotypes: DENV-1, DENV-2, DENV-3 and DENV-4. Choose the corresponding NS1 antigen for serotype-specific Research. A project studying antibody recognition across multiple serotypes may require a panel of DENV-1 through DENV-4 NS1 antigens. Where possible, select products with comparable sequence coverage, expression hosts, tags, concentrations and formulations. This reduces the number of variables affecting cross-serotype comparisons.

2. Confirm the NS1 sequence or protein region

An NS1 product may contain a complete sequence, a broad serotype-specific region or a selected immunodominant fragment. The product name alone does not confirm complete sequence coverage. For example, Recombinant Dengue NS1 N-terminal BLIT-0693 contains Type 2 N-terminal immunodominant regions. This construct may support Research directed at that region, while a study requiring other NS1 epitopes will need a broader or alternative construct.

Compare the listed amino-acid range with:

• The target antibody epitope
• Required structural region
• Assay design
• Desired molecular weight
• Need for full-length or partial protein

3. Choose an appropriate expression host

Beta LifeScience offers Dengue NS1 antigens produced using bacterial, insect-cell and mammalian-cell expression systems. The expression host may affect protein folding, processing, solubility and presentation.

4. Review tag and purity

A protein tag can support purification, detection or assay immobilization. Confirm its type and position before purchase because the tag may affect the way the antigen is presented. Purity should also match the intended application. Review both the reported percentage and the analytical method, such as SDS-PAGE.

5. Check formulation and quantity

Confirm the supplied buffer, concentration, package size and storage conditions. These details determine whether the antigen can be used directly or requires buffer exchange, dilution or other preparation.

E. coli vs Insect Cell vs HEK293-Expressed Dengue NS1

No single expression system is ideal for every Dengue NS1 project. The most suitable choice depends on the required sequence, antigen presentation and assay format.

E. coli-expressed Dengue NS1

E. coli is commonly used for recombinant antigen production. It can support defined protein fragments, serotype-specific antigens and tagged proteins.

Beta LifeScience’s E. coli NS1 range includes:

• N-terminal and C-terminal NS1 regions
• A general recombinant Dengue NS1 option
• DENV-1, DENV-3 and DENV-4 serotype-specific products

The NS1 N-terminal BLIT-0693 product is GST-tagged, >90% pure by SDS-PAGE and formulated in Tris-HCl with sodium chloride and glycerol. E. coli does not provide the same post-translational processing environment as insect or mammalian cells. The relevance of that difference depends on the targeted epitope and research application.

Insect-cell-expressed Dengue NS1

Beta LifeScience lists insect-cell-expressed NS1 products for DENV-1, DENV-2, DENV-3 and DENV-4. This makes the insect-cell range useful when a project requires multiple Dengue serotypes produced using the same broad type of expression platform. The DENV-4 insect-cell NS1 product, BLIT-0697, contains amino acids 776–1130 and has a reported purity above 95% by SDS-PAGE. Its listed applications include antibody ELISA, immunogen and Western blot research.

HEK293-expressed Dengue NS1

Recombinant NS1 DV2, BLIT-0590, provides a mammalian-cell-expressed DENV-2 option. It is produced in HEK293 cells, includes a C-terminal His tag and has a reported purity above 95%. The product is supplied as 100 µg at 1 mg/mL in PBS. Researchers can consider this format when their project specifically requires a HEK293-expressed DENV-2 NS1 antigen.

Expression host alone should not determine the purchase. Evaluate it together with the serotype, amino-acid range, tag, purity and assay requirements.

What Quality Information Should Buyers Check?

A buyer should review the product datasheet and available lot documentation before approving an order.

Important quality details include:

• Product identity and catalog number
• Dengue serotype
• Amino-acid range
• Expression host
• Tag type and position
• Molecular weight
• Purity and analytical method
• Protein concentration
• Buffer formulation
• Package size
• Storage instructions
• Certificate of Analysis availability
• Recommended research applications

Purity and SDS-PAGE

SDS-PAGE is commonly used to evaluate the apparent molecular weight and purity of recombinant proteins. The reported percentage should be considered together with the expected protein size, tag and assay requirements.

Formulation

Some Dengue NS1 products are supplied in PBS, while others use product-specific buffers containing salts, glycerol or stabilizing components. Review the complete formulation before using an antigen in coating, conjugation or binding workflows.

Application fit

Beta LifeScience lists research applications such as antibody ELISA, immunogen studies and Western blotting for selected NS1 products. These descriptions indicate potential use but do not replace optimization and validation in the buyer’s assay. All products discussed here should be handled according to their stated For Research Use Only designation. They are research reagents rather than standalone clinical diagnostic products.
