一般描述
IL-4 can signal through type I and type II receptor complexes, which share a common gamma chain (gc). The type I receptor contains in addition to the gc an IL-4Rα subunit, whereas the type II receptor contains the IL-13Ra. The secreted extracellular domain of IL-4Ra, called sIL-4Ra, binds IL-4 and antagonizes its activity. It plays an important role in regulating the differentiation of naïve CD4+ T cells and class switching to IgG1 and IgE. Recombinant human sIL-4Rα is a 209 amino acid protein which corresponds to the entire extracellular domain of IL-4Rα.

外形
Lyophilized from 1x PBS pH 7.0.
重悬
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8℃ for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20℃ to -80℃.
