Rabbit Polyclonal IFNA2 Antibody

The IFNA2 antibody is a tool used to detect and study interferon-alpha 2 (IFNA2), a cytokine belonging to the type I interferon family. IFNA2 plays a critical role in innate immunity, particularly in antiviral responses and antitumor activity. It binds to the interferon-α/β receptor (IFNAR), activating JAK-STAT signaling pathways to induce expression of interferon-stimulated genes (ISGs) that inhibit viral replication and modulate immune cell functions. IFNA2 antibodies are widely employed in research to quantify protein levels, assess expression patterns, and explore its involvement in diseases such as chronic viral infections (e.g., hepatitis B/C), autoimmune disorders (e.g., lupus), and cancers. These antibodies are utilized in techniques like ELISA, Western blotting, immunohistochemistry, and flow cytometry. Monoclonal IFNA2 antibodies offer high specificity, while polyclonal versions may detect broader epitopes. Researchers select antibodies based on applications, ensuring validation for sensitivity and cross-reactivity, as some interferons share structural homology. Dysregulation of IFNA2 is linked to pathological conditions, making its antibody a valuable reagent for mechanistic studies, biomarker discovery, and therapeutic development targeting interferon pathways.
