Description

Rubella E2 Envelope Protein CAS NO 131016-03-0 is a highly purified recombinant protein antigen derived from the E2 glycoprotein of the Rubella virus. This critical reagent is essential for the development and quality control of diagnostic assays, vaccine research, and immunological studies. It is primarily utilized by biotechnology, pharmaceutical, and in-vitro diagnostic (IVD) manufacturers requiring consistent, high-quality viral antigens.

Application

• Immunoassay Development: Key component for ELISA, CLIA, and lateral flow assays for Rubella antibody detection.
• Vaccine Research: Used in immunogenicity studies and as a reference standard for vaccine potency testing.
• Diagnostic Kit Manufacturing: Coated antigen for commercial serology test kits to detect Rubella IgG/IgM.
• Clinical Research: Tool for investigating host immune response and Rubella virus pathogenesis.
• Quality Control (QC): Reference material for lot-to-lot consistency testing of diagnostic products.
• Antibody Production: Immunogen for generating monoclonal and polyclonal antibodies in animal models.

Quality Control

Our Rubella E2 Envelope Protein is manufactured under stringent quality systems. Each lot undergoes comprehensive analytical testing including SDS-PAGE, Western Blot, and HPLC for purity and identity, and is functionally validated for immunoassay performance. A detailed Certificate of Analysis (COA) documenting purity, endotoxin levels, and biological activity is provided with every shipment to ensure it meets the exacting standards for diagnostic and research use.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below in a non-frost-free freezer. Avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature before opening to prevent condensation.
