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.
ELISA:<br>Direct:<br>To detect hIL-31 by direct ELISA (using 100 ?L/well antibody solution) a concentration of 0.25 - 1.0 ?g/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with compatible secondary reagents, allows the detection of at least 0.2 - 0.4 ng/well of recombinant hIL-31.<br><br>Sandwich<br>To detect hIL-31 by sandwich ELISA (using 100 ?L/well antibody solution) a concentration of 0.25 - 1.0 ?g/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with our polyclonal Anti-Human IL-31 as a capture antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant hIL-31. <br><br>Western Blot:<br>To detect hIL-31 by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 ?g/mL. Used in conjunction with compatible secondary reagents the detection limit for recombinant hIL-31 is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
The reconstituted antibody can temporarily be stored at 2-8°C. Long term storage at -20°C or below. Avoid repeated freeze-thaw cycles.
