<strong>Figure 4 Immunofluorescence Validation of IL-23 in Mouse Pancreas Tissue</strong><br>Immunofluorescent analysis of 4% paraformaldehyde-fixed mouse pancreas tissue labeling IL-23 with 3795 at 20 μg/mL, followed by goat anti-rabbit IgG secondary antibody at 1/500 dilution (red).
<strong>Figure 5 Immunohistochemistry Validation of IL-23 in Mouse Pancreas Tissue </strong><br> Immunohistochemical analysis of paraffin-embedded mouse pancreas tissue using anti-IL-23 antibody (3795) at 2 μg/ml. Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4° C. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.
<strong>Figure 6 Induced Expression Validation of IL-23 in Mouse Keratinocytes of Epidermis (Yoon et al., 2016) </strong><br>The expression of IL-23 protein induced by tape stripping was detected by immunohistochemical analysis of mouse's skin with anti-IL-23 antibodies. Skin sections from the mouse exhibited epidermis staining positive for IL-23 expression 6 hr after tape stripping. Staining with an isotype-matched irrelevant antibody (Ctrl IgG) was used as a negative control.

Background:
IL-23 Antibody: Like interleukin-27 (IL-27), IL-23 is a recently discovered member of the IL-6/IL-12 family of proinflammatory and immunoregulatory cytokines. It exists as a heterodimer composed of the IL-12p40 subunit and a novel p19 subunit. IL-23 is secreted by activated dendritic cells, macrophages, and monocytes. Its biological activities include enhancing the proliferation of memory T cells and the production of IFN-gamma, IL-12, and TNF-α from activated T cells, and can stimulate macrophages to produce TNF-α and nitric oxide. It has also been shown to possess potent anti-tumor and anti-metastatic activity in mouse models of cancer, suggesting a potential role for IL-23 in therapeutic treatment of cancer.
