    IL-12B p40 Antibody (1-1A4) is a mouse monoclonal IgG1 antibody that detects IL-12B p40 in human samples through applications such as western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). IL-12B p40 plays a crucial role in the immune response as a subunit of the heterodimeric cytokine IL-12, which is essential for the differentiation of naive CD4(+) T cells into type 1 helper T cells that produce interferon-γ (IFN-γ). This process is vital for the activation of T and natural killer (NK) cells, which are key players in the body′s defense against infections and tumors. Additionally, IL-12B p40 can combine with p19 to form IL-23, another important cytokine that shares some functional properties with IL-12, including the activation of the transcription factor Stat4 and the promotion of IFN-γ production. IL-12B p40′s ability to influence both IL-12 and IL-23 pathways highlights its significance in regulating immune responses and maintaining immune homeostasis. Anti-IL-12B p40 antibody (1-1A4) serves as an invaluable tool for researchers studying cytokine signaling and immune system dynamics.
