    Background:
IL-31 is a recently discovered helical cytokine, belonging to the gp130/IL-6 cytokine family.The receptors for IL- 6 family are type I receptors, and they share a number of common structural motifs, such as the cytokine-binding domain with two pairs of conserved cysteine residues and a WSXWS sequence motif in the extracellular domain. IL-31 is expressed preferentially by activated Th2 CD4+ T cells, signaling through a heterodimeric receptor complex composed of IL-31RA and OSMR. Recent studies in both humans and mice have suggested a link between IL- 31/IL-31R expression and skin inflammation although the functional significance of endogenous IL-31/IL-31R interactions in influencing innate and adaptive immune responses remains unknown.
            Description:
Recombinant Interleukin-31 is a disulfide-linked monomer protein consisting of 142 amino acid residues, and migrates as an approximately 18 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Interleukin-31 mature chain was expressed in E. coli.
            UniProt
 Q6EBC2
            Synonym(s):
 IL-31, interleukin 31 , IL31
            Purity:
 ≥95% by SDS-PAGE and HPLC
            Endotoxin Level:
  <0.1 ng/µg (1 EU/µg), using the LAL gel clot method. 
            Biological Activity:
 The ED50 was determined by the ability to induce STAT3 activation in U87MG cells, and was determined to be ≥ 7 ng/ml.
            Formulation:
 Lyophilized from a 0.2 µm filtered PBS solution, pH 7.5.
            Format:
 lyophilized protein
            Reconstitution:
 Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid. 
            Storage / Stability:
The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
