Western Blotting (WB), ELISA, Immunofluorescence (IF)
Purification
IL-31 Antibody is affinity chromatography purified via peptide column.
Immunogen
IL-31 antibody was raised against a 18 amino acid synthetic peptide from near the center of human IL-31. The immunogen is located within amino acids 60 - 110 of IL-31.
IL-31 antibody can be used for the detection of IL-31 by Western blot at 2.5 - 10 μ,g/mL. Despite its predicted size, IL-31 runs at approximately 27 - 30 kDa in SDS-PAGE. For immunofluorescence start at 20 μ,g/mL.
Antibody validated: Western Blot in human samples and Immunofluorescence in human samples. All other applications and species not yet tested.

IL-31 Antibody: Interleukin-31 (IL-31) is a recently discovered T-cell cytokine closely related to IL-6 type cytokines and is preferentially produced by T helper type 2 cells. IL-31 activity is mediated through the ligand-induced oligomerization of a dimeric receptor complex containing IL-31 receptor A and oncostatin M receptor. In response to IL-31 binding, these proteins activate the JAK/STAT and the AKT signaling pathways. RNA levels of IL-31 receptor A and oncostatin M receptor are induced in activated monocytes but are expressed constitutively in epithelial cells. IL-31, when overexpressed in transgenic mice, results in the development of pruritis, alopecia, and skin lesions and in humans may result in atopic dermatitis, suggesting that IL-31 may represent a novel target for antipruritic drug development.
