Primary Accession | Q6EBC2 |
---|---|
Species | Human |
Sequence | Ser24-Thr164 |
Purity | > 97% as analyzed by SDS-PAGE > 97% as analyzed by HPLC |
Endotoxin Level | < 1 EU/ µg of protein by LAL method |
Biological Activity | Fully biologically active when compared to standard. The specific activity is determined by inducing STAT3 activation using human U-87 MG cells. 5.0 ng/ml of rHuIL-31 can effectively induce STAT3 activation. |
Expression System | E. coli |
Theoretical Molecular Weight | 15.8 kDa |
Formulation | Lyophilized from a 0.2 µm filtered solution in PBS, pH 7.4. |
Reconstitution | It is recommended that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute the lyophilized powder in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/ml. |
Storage & Stability | Upon receiving, this product remains stable for up to 6 months at -70°C or -20°C. Upon reconstitution, the product should be stable for up to 1 week at 4°C or up to 3 months at -20°C. Avoid repeated freeze-thaw cycles. |
Gene ID | 386653 |

Other Names | Interleukin-31, IL-31, IL31 |
Target Background | Human IL-31 is a T-cell derived cytokine that shares several structural and functional characteristics with IL-6, Oncostatin M, LIF, and Cardiotrophin-1. It signals through a receptor complex comprised of GPL (GP130-like, IL-31RA) and OSMR (Oncostatin M receptor). GPL/OSMR signaling is a strong activator of STAT3 and STAT5, and can also activate STAT1, Jak1, and Jak2 signaling pathways. IL-31 regulated immune responses have been implicated in skin physiology and inflammatory skin diseases. |
Name | IL31 |
---|---|
Function | Activates STAT3 and possibly STAT1 and STAT5 through the IL31 heterodimeric receptor composed of IL31RA and OSMR (PubMed:15184896). May function in skin immunity (PubMed:15184896). Enhances myeloid progenitor cell survival in vitro (By similarity). Induces RETNLA and serum amyloid A protein expression in macrophages (By similarity). |
Cellular Location | Secreted. |
Tissue Location | Detected at low levels in testis, bone marrow, skeletal muscle, kidney, colon, thymus, small intestine and trachea |
