Description

E9 Protein, Papillomavirus is a recombinant protein derived from the E9 region of the human papillomavirus (HPV). This high-purity protein is a critical reagent for advanced virology research and diagnostic assay development. It is primarily utilized by biotechnology and pharmaceutical companies engaged in vaccine research, antiviral drug discovery, and the production of immunodiagnostic kits.

Application

• Vaccine Research & Development: Used as a key antigen for immunogenicity studies and the development of next-generation HPV vaccines.
• Diagnostic Assay Production: Serves as a critical coating antigen or standard in ELISA, chemiluminescence, and other immunoassays for HPV antibody detection.
• Antiviral Drug Screening: Employed in high-throughput screening (HTS) platforms to identify compounds that inhibit HPV protein function.
• Biochemical Research: Essential for studying HPV protein structure, function, and host-cell interaction mechanisms.
• Reference Standard: Acts as a purified standard for quality control and calibration in diagnostic manufacturing.
• Antibody Production & Characterization: Used to immunize animals for polyclonal or monoclonal antibody generation and for subsequent antibody specificity testing.
