Mouse IL-4 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 PBS,pH7.4. 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: Mouse Target: Il4 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:Mouse Interleukin-4(IL-4) is a monomeric, Th2 cytokine that shows pleiotropic effects during immune responses. It is a glycosylated polypeptide that contains three intrachain disulfide bridges and adopts a bundled four alphaŁhelix structure. ILŁ4 exerts its effects through two receptor complexes, Participates in at least several B-cell activation processes as well as of other cell types. ILŁ4 is primarily expressed by Th2Łbiased CD4 T cells, mast cells, basophils, and eosinophils. It promotes cell proliferation, survival, and immunoglobulin class switch to IgG1 and IgE in mouse B cells, acquisition of the Th2 phenotype by na’ve CD4 T cells, priming and chemotaxis of mast cells, eosinophils, and basophils, and the proliferation and activation of epithelial cells. ILŁ4 plays a dominant role in the development of allergic inflammation and asthma. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes.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.
