商品介绍
Species: Human
Host Species: E. coli
MW: 18 kDa
Genbank #: Q6EBC2
a.a: 24–164
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.
