Description

Definition and Structure

IL12A Antibody is a monoclonal antibody that binds exclusively to the p35 subunit of IL-12, which forms a heterodimer with the p40 subunit (encoded by the IL12B gene) to constitute the biologically active IL-12 cytokine . The antibody is engineered to recognize epitopes on the IL12A protein, enabling its detection in assays such as Western blot, ELISA, and immunoprecipitation .

Key Features of IL12A Antibody

  • Isotype: Typically IgG (e.g., clone OTI2A8 from OriGene) .

  • Specificity: Targets the 35-kDa alpha chain of IL-12, distinguishing it from other IL-12 family members (e.g., IL-23, IL-27) .

  • Cross-reactivity: Limited to human IL12A, with no reported reactivity to murine or other species .

Biological Function of IL12A

IL12A is critical for immune system regulation, particularly in:

  • Th1 Cell Differentiation: Drives naive T cells toward Th1 lineage, enhancing cell-mediated immunity .

  • NK Cell Activation: Stimulates interferon-gamma (IFN-γ) production and cytotoxic activity in natural killer (NK) cells .

  • Anti-Angiogenic Effects: Indirectly inhibits tumor angiogenesis via induction of IP-10/CXCL10 .

Research Applications

The IL12A Antibody is a versatile tool in immunology and oncology research:

ApplicationMethodPurpose
Western BlotSDS-PAGE/ImmunoblotDetect IL12A expression in lysates from dendritic cells, macrophages, or tumors .
ELISASandwich AssayQuantify IL12A levels in serum or supernatants .
ImmunoprecipitationCo-IPStudy IL12A-protein interactions (e.g., with IL12B, STAT4) .
Flow CytometryIntracellular StainAnalyze IL12A expression in antigen-presenting cells .

Challenges and Considerations

  • Cross-reactivity: Requires validation to ensure specificity for IL12A versus IL-35 (formed with EBI3) .

  • Regulatory Status: For research use only; not approved for clinical diagnostics .

  • Toxicity in Therapeutics: While IL12A-based therapies show promise, systemic administration risks cytokine release syndrome (CRS), necessitating localized delivery .

Future Research Directions

Emerging studies focus on:

  • Cancer Immunotherapy: Engineering tumor-targeted IL12A antibodies to enhance anti-tumor immunity while minimizing toxicity .

  • Autoimmune Diseases: Investigating IL12A’s role in conditions like psoriasis, where IL12/IL23 inhibitors are already in use .

Target Background

Function
IL12A is a cytokine that acts as a growth factor for activated T and NK cells. It enhances the lytic activity of NK/lymphokine-activated killer cells and stimulates the production of IFN-gamma by resting PBMC.
