生物活性 Measured by its ability to inhibit IL-4-dependent proliferation of TF-1 human erythroleukemic cells. The ED50 for this effect is 5-20 ng/mL.
纯度 > 95% as determined by reducing SDS-PAGE.
内毒素 < 0.1 EU/μg
制剂 Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
复融 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 sterile water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
储存条件 Lyophilized protein should be stored at -5~-20℃, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at -5~-20℃ for 3 months.
运输条件 Ambient temperature or ice pack.
有效期 12个月
背景介绍 Interleukin 4 Receptor alpha (IL4-Ra) is a widely expressed 140 kDa transmembrane glyco Protein in the class I Cytokine Receptor family. Mature human IL4-Ra consists of a 207 amino acid (aa) extracellular domain (ECD) that contains a Cytokine binding region and one fibronectin type III domain, a 24 aa transmembrane segment, and a 569 aa cytoplasmic domain that contains one Box 1 Motif and one ITIM Motif. IL4-Ra plays an important role in Th2-biased immune responses, alternative macrophage activation, mucosal immunity, allergic inflammation, tumor progression, and atherogenesis. Soluble forms of IL4-Ra, generated by alternate splicing or proteolysis, retain Ligand binding properties and inhibit IL-4 bioactivity. IL4-Ra is a component of two distinct Receptor complexes and shows species selectivity between human and mouse. It can associate with the common gamma chain (γc) to form the IL-4 responsive type I Receptor in which γc increases the affinity for IL-4 and enables signaling. It can alternatively associate with IL13-Ra1 to form the type II Receptor which is responsive to both IL-4 and IL-13. The use of shared Receptor components contributes to the overlapping biological effects of IL-4 and IL-13 as well as other Cytokines that utilize γc.
