Human IL-20 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: IL20 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:
Interleukin-20 (IL-20) is a member of the IL-10 family of regulatory cytokines that includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26. Members of this family share partial homology in their amino acid sequences but they are dissimilar in their biological functions. IL-20 exhibits approximately 28% amino acid identity with IL-10 and 76% amino acid identity with mouse IL-20. There are two heterodimeric receptor complexes for IL-20. The first is composed of IL-20 R alpha and IL-20 R beta . The second is composed of IL-22 R and IL-20 R beta . Whereas the IL-22 R/IL-20 R beta complex is shared with IL-24, the IL-20 R alpha/IL-20 R beta complex is shared with both IL-19 and IL-24. IL-20 has been shown to initiate transduction cascades involving STAT3 and stimulates the induction of pro-inflammatory genes including TNF- alpha and MCP-1. Initial functional studies using transgenic mice suggest that IL-20 has the ability to regulate skin development. The over-expression of both human and mouse forms of IL-20 results in keratinocyte hyper-proliferation, abnormal epidermal differentiation, and neonatal lethality. In humans, IL-20 and its receptors are up-regulated in psoriatic skin, and polymorphisms in the IL-20 gene have been associated with plaque-type psoriasis. IL-20 may also have a role in hematopoiesis. It enhances the proliferation of multi-potential progenitors in vitro and increases their numbers and cell cycling status in IL-20 transgenic mice. IL-20 is also shown to suppress COX-2 and PGE2 and acts as an inhibitor of angiogenesis in model systems.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.
