How to Select the Right Product

Identify your need: Recombinant antigen for assay development? Detection antibody for diagnostics? ELISA kit for quantification?
Antigen selection: Choose full-length proteins for broad reactivity or domain/fragment for epitope-specific applications and lower background.
Antibody pairing: Use monoclonal pairs for sandwich ELISA with high specificity; polyclonal for Western blot detection and capture assays.
Quality requirements: Specify endotoxin level (≤0.1 EU/µg for cell-based), purity grade (≥90%), and volume needs for your downstream application.

FAQs

What reagent types are available for this virus?

We offer recombinant antigens (full-length, fragments, key epitopes), monoclonal & polyclonal detection antibodies, and ELISA kits for quantitative measurement.

Are your viral antigens suitable for diagnostic R&D?

Yes. Our antigens are produced under ISO 9001/13485 quality systems with low endotoxin, high purity (≥90%), and confirmed batch-to-batch consistency.

What expression systems are used for viral proteins?

HEK293/CHO for glycoproteins and complex antigens requiring native conformation; E. coli for nucleocapsid and simpler structural proteins.

How should I select between mAb and pAb?

Monoclonal antibodies provide epitope specificity for sandwich ELISA and diagnostic applications. Polyclonal antibodies offer broader recognition for Western blot and capture assays.

Do you offer matched antibody pairs for assay development?

Yes — we provide validated capture/detection antibody pairs for sandwich ELISA development. Contact us for pairing recommendations and bulk pricing.
