Active GMP Recombinant Human IL31 protein

• Cat.No.: IL31-4336HG
• Product Overview: Recombinant Human IL31 was produced in E. coli using non-animal reagents in an animal-free facility under cGMP guidelines.

Specification

• Description: Human Interleukin-31 (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.
• Source: E. coli
• Species: Human
• Form: Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH7.4.
• Bio-activity: The specific activity is determined by inducing STAT3 activation using human U-87 MG cells. 5 ng/mL of IL31 can effectively induce STAT3 activation.
• Molecular Mass: Approximately 15.8 kDa, a single non-glycosylated polypeptide chain containing 141 amino acids.

• Endotoxin: Less than 1 EU/μg of the protein by LAL method.
• Purity: >97% by SDS-PAGE and HPLC analyses.
• Storage: This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably des centigradecated. Upon reconsitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 centigrade to -70 centigrade. Avoid repeated freeze/thaw centigrade centigradeles.
• Reconstitution: Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 centigrade. Further dilutions should be made in appropriate buffered solutions.
• Quality Statement: Our GMP proteins are produced according to relevant sections of the following documents: WHO TRS, No. 822, 1992 Annex 1, Good Manufacturing Practices for Biological Products; USP Chapter 1043, Ancillary Materials for Cell, Gene and Tissue-Engineered Products and USP Chapter 92, Growth Factors and Cytokines Used in Cell Therapy Manufacturing.
• Shipping: The product is shipped at ambient temperature. Upon receipt, store it immediately at the recommended temperature.
