背景说明： Human Interleukin 31 (IL-31) is a cytokine containing a four-helix bundle structure.It shares several structural and functional characteristics with IL-6，Oncostatin M，LIF，and Cardiotrophin-1.Human IL-31 cDNA encodes a 164 amino acid precursor that contains a 23 amino acid signal peptide and a 141 amino acid mature protein.Human and mouse IL-31 share 24% sequence identity in the mature region.IL-31 is mainly associated with activated T cells and is preferentially expressed by type 2 helper T cells (Th2).IL-31 signals via a heterodimeric receptor complex composed of a gp130 related molecule termed IL-31RA (also GPL and GLMR) and an Oncostatin M receptor (OSM Rβ).The IL-31 receptor is constitutively expressed by keratinocytes and upregulated by IFNγ on monocytes.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.Studies have shown that IL31 induces severe pruritis (itching) and dermatitis in transgenic mice.

溶剂： Always centrifuge tubes before opening.Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 μg/ml.Dissolve the lyophilized protein in ddH2O.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
内毒素： Less than 0.1 ng/ug(1 IEU/ug)as determined by LAL test.

Recombinant Human Interleukin-31 is produced by our E.coli expression system and the target gene encoding Ser24-Thr164 is expressed.
