HOST SPECIES:Rabbit
SPECIES REACTIVITY: Human, Mouse
HOMOLOGY: Predicted species reactivity based on immunogen sequence: Horse: (94%), Pig: (82%), Rat: (76%), Guinea pig: (76%)
IMMUNOGEN: Anti-IL-23 antibody (3795) was raised against a peptide corresponding to 17 amino acids near the amino terminus of human IL-23.

The immunogen is located within amino acids 40 - 90 of IL-23.
TESTED APPLICATIONS: ELISA, IF, IHC-P, WB
APPLICATIONS: WB: 0.25-2 μg/mL; IF: 20 μg/mL, IHC: 2 μg/mL.

Antibody validated: Western Blot in human and mouse samples; Immunofluorescence and Immunohistochemistry in mouse samples. All other applications and species not yet tested.
POSITIVE CONTROL:1) Cat. No. 1414 - Mouse Pancreas Tissue Lysate
PREDICTED MOLECULAR WEIGHT: Predicted: 21kD

Observed: 22 kD
psi-iconAdvanced Validation
VALIDATION:

Recombinant Protein Test (Figure 2): Anti-IL-23 antibodies (3795) detected human IL-23 recombinant protein at different concentrations.

 

Induced Expression Validation (Figure 6): IL-23 expression detected by anit-AIF antibodies was up-regulated by tape stripping.

ISOFORMS: Human IL-23 has one isoform (189aa, 20.7kD). Mouse IL-23 has one isoform (196aa, 22.1kD) and Rat IL-23 also has one isoform (196aa, 22kD). 3795 can detect human and mouse, and possibly detect rat.

psi-iconBackground and References
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.
