Mouse IL-13 (Ser26-Phe131) 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, 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: Mouse Target: Il13 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 13 (mIL-13) is a pleiotropic cytokine produced by activated Th2 cells. IL-13 induces B cell proliferation and immunoglobin production. It contains a four helical bundle with two internal disulfide bonds. Mouse IL13 shares 58% sequence identity with human protein and exhibits cross-species activity. IL13 signals via receptor IL13R (type2, IL4R) and activates STAT-6. IL13 initially binds IL-13R alpha1 with low affinity and triggers association of IL4R alpha, generating a high affinity heterodimeric receptor IL13R and eliciting downstream signals. IL13 also binds IL-13R alpha2 with high affinity, which plays a role in a negative feedback system of IL13 signaling. IL13 is an important mediator of allergic inflammation and disease.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.
