Human IL-31 Recombinant Protein Tag Free Lyophilized from Innovative Research has been recombinantly produced in E. coli. This is a Lyophilized protein buffered in Lyophilized from a 0.2 um filtered solution of 20mM PB, 150mM NaCl, pH 7.4. It is not recommended to reconstitute to a concentration less than 100UG/ml. Dissolve the lyophilized protein in ddH2O. with a purity of Greater than 95% as determined by reducing SDS-PAGE.Endotoxin level less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test..More Details: Species: Human Target: IL31 Purity: Greater than 95% as determined by reducing SDS-PAGE.Endotoxin level less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. Source: E. coli Storage Conditions: Lyophilized protein should be stored at -20░C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7░C for 2-7 days.Aliquots of reconstituted samples are stable at -20░C for 3 months.

Additional Information:

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 R beta ). The IL-31 receptor is constitutively expressed by keratinocytes and upregulated by IFN gamma 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.This recombinant protein can be used for biological assays. For research use only. . At Innovative Research we provide reliable, consistent products that deliver reliable, consistent results.
