IL-12B p40 Antibody (C17.8) is a rat monoclonal IgG2a antibody that detects IL-12B p40 in mouse samples through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). IL-12B p40 plays a crucial role in the immune response as a subunit of the heterodimeric cytokine interleukin-12 (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 interleukin-23 (IL-23), a cytokine that shares some functional properties with IL-12, including the activation of the transcription factor Stat4 and the promotion of IFN-γ production. The ability of IL-12B p40 to influence both IL-12 and IL-23 pathways highlights its importance in regulating immune responses and maintaining immune homeostasis, making anti-IL-12B p40 antibody (C17.8) a valuable tool for researchers studying cytokine signaling and immune function in mouse models.

could i know what is the difference between using the FUll length Versus the L from IL12B p40 C17.8; sc-57258? is the L one manufacture for not detect the heterodimer of the il12 protein

Asked by: Shorouk
Thank you for the question. The "L" form on the antibody is just an azide-free form of the antibody, usually used for neutralization studies, sc-57258 L. It is the same antibody as the non L form, so they will both detect the same protein.

I bought the L form of this antibody, sc-57258 L for blocking (neutralization). How long can I store this at in the refridgerator?

Asked by: AbPolly
The L form of the antibody should be stored at -20°C. Once thawed, we recommend using as soon as possible, although it is usually stable for up to 2 weeks at 4 degrees.
