Gibco™ Human IL-4 Receptor alpha (soluble) Recombinant Protein, PeproTech®

Description

Recombinant Protein

PeproTech's CHO cell-derived Recombinant Human sIL-4 Receptor alpha is a 23.9 kDa glycoprotein corresponding to 209 amino acid residues of the extracellular domain of IL-4Ralpha. As a result of glycosylation, Recombinant Human sIL-4 Receptor alpha migrates with an apparent molecular mass of approximately 50-65 kDa by SDS-PAGE gel, under reducing conditions. This product is shipped at ambient temperature. For storage, handling and reconstitution information, please see the lot-specific Certificate of Analysis

IL4 Receptor alpha (IL4RA) is the alpha chain of the interleukin 4 receptor which binds to both interleukin 4 and interleukin 13 to regulate IgE production, chemokine and mucus production at sites of allergic inflammmation. The IL4 response is involved in promoting Th2 differentiation. The secreted extracellular domain of IL4R alpha, called sIL4R alpha, can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells. It has no signaling abilities. Allelic variations in the IL4RA gene have been associated with atopy, a condition that can manifest itself as allergic rhinitis, sinusitus, asthma, or eczema.
