IL-31 (Interleukin-31), Human
Interleukin-31 (IL-31) s an inflammatory cytokine that helps trigger cell-mediated immunity against pathogens. It has also been identified as a major player in a number of chronic inflammatory diseases, including atopic dermatitis. It is produced by a variety of cells, namely type 2 helper (TH2) T-cells. IL-31 sends signals through a receptor complex made of IL-31RA and oncostatin M receptor β (OSMRβ) expressed in immune and epithelial cells. These signals activate three pathways: ERK1/2 MAP kinase, PI3K/AKT, and JAK1/2 signaling pathways.

Ser24-Thr164
UnitProt ID:
Q6EBC2
Source:
Escherichia coli
Endotoxin Test:
<0.1 EU per 1 μg of the protein by the LAL method.
Activity:
Measured by its ability to induce A549 cells proliferation. The ED50 for this effect is < 40 ng/mL.
Purity:
>98% as determined by SDS-PAGE.
Form:
Lyophilized
Storage Buffer:
Lyophilized from a 0.2 μm filtered solution of PBS, pH 8.0.
Reconstitution:
It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Stability & Storage:
This product is stable after storage at:
• -20°C for 12 months in lyophilized state from date of receipt.
• -20°C or -80°C for 1 month under sterile conditions after reconstitution.
Avoid repeated freeze/thaw cycles.
