IL-31 Recombinant Protein

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. Recombinant murine IL-31 is a 15.8 kDa protein containing 140 amino acid residues.

The lyophilized IL-31 recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted IL-31 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing IL-31 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
