Varicella-Zoster Virus (VZV) Extract Antigen

Manufactured and quality-controlled for use as a coated or probed viral antigen in immunology assays, this native VZV preparation from Antibodies.com is supplied as an inactivated infected cell extract enriched for viral proteins from Strain Ellen propagated in NHDF cells. Each25 mL liquid aliquot is formulated in 100 mM Glycine buffer at pH 9.5 and is provided at a lot-specific concentration of approximately 0.5 mg/mL, offering a consistent reagent for ELISA (EIA) and Western Blot (WB) workflows. Inactivation has been confirmed by tissue culture infectivity assay, and every lot has been verified negative for HIV and Hepatitis B virus, supporting safe handling under standard BSL-2 practices. The material is intended for research use only and is shipped on dry ice for long-term storage at ≤ -70 °C, where the glycoprotein-rich viral extract remains stable for repeated freeze-thaw cycles when aliquoted. Researchers studying humoral responses to Varicella-Zoster Virus, developing varicella or shingles serology panels, or generating positive-control antigens for immunoblot assays can rely on the Ellen-strain specificity preserved in this NHDF-derived cell extract. As with all native viral antigens, brief centrifugation is recommended if any liquid is observed in the cap, and the reagent should be treated as potentially infectious even after validated inactivation.
