HBV env (183–191)

HBV env (183–191) is a synthetic peptide fragment derived from the Hepatitis B virus envelope protein, specifically corresponding to amino acid residues 183 to 191. This high-purity research peptide, characterized by the molecular formula C₅₃H₉₂N₁₂O₁₂ and a molecular weight of 1089.4 Da, serves as a critical antigenic tool for virology and immunology research. While a specific CAS Number is typically assigned to bulk chemical substances, this peptide is identified by its sequence (YLS-PFP-WNW) and is widely used as a standard or immunogen in the development of diagnostic assays and therapeutic antibodies targeting Hepatitis B. Its well-defined structure ensures consistency in experimental results.

1.MECHANISM OF ACTION

Antigenic Mimicry: The peptide mimics the native epitope found on the Hepatitis B virus (HBV) surface, allowing it to bind specifically to HBV-specific antibodies and T-cell receptors.

Immune Recognition: It functions by stimulating an immune response in vitro, serving as a target for neutralizing antibodies or cytotoxic T-lymphocytes (CTLs) in research settings.

Signal Transduction: Used as a probe to study the interaction between viral antigens and host immune cells, aiding in the understanding of viral entry and immune evasion mechanisms.

2.PRODUCT INDICATIONS

Research Use Only (RUO): Strictly intended for scientific research, not for diagnostic or therapeutic use in humans.

Diagnostic Development: Ideal for coating ELISA plates or generating standards for immunoassays designed to detect HBV antibodies.

Vaccine Research: Useful as an immunogen in the development of novel vaccine candidates or therapeutic vaccines against chronic HBV infection.

Antibody Production: Serves as an immunizing antigen for the production and purification of polyclonal or monoclonal antibodies specific to the HBV envelope.

3.CLINICAL EFFICACY OF PRODUCT

High Specificity: Demonstrates high binding affinity to known anti-HBV antibodies, ensuring accurate and reliable data in competitive binding assays.

Batch Consistency: With a defined molecular weight (1089.4 Da) and sequence, it provides reproducible results across different experimental batches, which is crucial for pre-clinical validation.

Therapeutic Monitoring: Can be utilized as a reference molecule to assess the titer and efficacy of patient-derived antibodies in studies focusing on functional cures for Hepatitis B.
