TNF-α (72-82), human

<p>TNF-α (72-82), human is a synthetic, 11-amino acid peptide corresponding to residues 72-82 of the mature human Tumor Necrosis Factor-alpha (TNF-α) protein. This research-grade peptide represents a specific linear epitope or functional region within the cytokine. It serves as a specialized tool for immunology and antibody research, particularly for mapping antibody binding sites, studying TNF-α structure-function …

1.MECHANISM OF ACTION

This peptide itself does not possess the native trimeric structure or full biological activity of the intact TNF-α cytokine. Its mechanism is primarily antigenic. The sequence represents a portion of the solvent-exposed surface of the native TNF-α protein. As a linear epitope, it can be specifically recognized and bound by monoclonal or polyclonal antibodies raised against human TNF-α. It may also interact with certain TNF receptors or neutralizing agents, providing insights into critical binding interfaces. The peptide's utility lies in probing interactions and blocking specific regions without triggering full receptor activation.

2.PRODUCT INDICATIONS

This product is indicated for specialized applications in immunology and biotechnology development. Key uses include: mapping the epitope specificity of anti-TNF-α monoclonal antibodies in antibody characterization and hybridoma screening; serving as a coating antigen or competitor in enzyme-linked immunosorbent assays (ELISAs) to detect TNF-α or anti-TNF antibodies; studying structure-activity relationships by targeting specific regions of the TNF-α molecule; and as an immunogen for generating antibodies against this specific region of TNF-α.

3.CLINICAL EFFICACY OF PRODUCT

TNF-α (72-82), human is a research and diagnostic development tool, not a therapeutic. Its clinical relevance and efficacy are indirect but crucial. It is used extensively in the pharmaceutical industry for the quality control and characterization of biologic drugs. Specifically, it is vital for: 1) Biosimilar Development: Confirming that a biosimilar antibody binds to the same epitope as the reference anti-TNF drug (e.g., adalimumab, infliximab). 2) Antibody Drug Characterization: Defining the precise binding site of therapeutic anti-TNF antibodies, which is a critical quality attribute. 3) Diagnostic Development: Helping to create specific assays to monitor drug levels or anti-drug antibodies in patients undergoing anti-TNF therapy.
