    IFN-α2 Antibody (9D3) is a mouse monoclonal IgG1 antibody that detects IFN-α2 in human samples through applications such as western blotting (WB) and enzyme-linked immunosorbent assay (ELISA). IFN-α2, a member of the type I interferon family, plays a crucial role in the immune response by inducing antiviral activity and modulating the immune system. This cytokine is primarily produced by leukocytes in response to viral infections and is essential for the activation of immune cells, including natural killer cells and macrophages, which are vital for controlling viral replication and tumor growth. The importance of IFN-α2 extends to therapeutic applications, as IFN-α2 is increasingly utilized in clinical settings to treat various malignancies, myelodysplastic syndromes, and autoimmune diseases. Additionally, IFN-α2 interacts with the type I interferon receptor, which is a multisubunit receptor that also binds other interferons, thereby amplifying the immune response. The ability of IFN-α2 to modulate immune pathways makes IFN-α2 a significant target for research and therapeutic interventions, highlighting the relevance of anti-IFN-α2 antibody (9D3) in advancing our understanding of immune regulation and treatment strategies.
