Recombinant Human IL4R, Fc-tagged

• Cat.No.: IL4R-28641TH
• Product Overview: Recombinant fragment, corresponding to the signal peptide and extracellular amino acids 1-232 of Human IL4R fused to the Fc region of human IgG1. The chimeric protein was expressed in modified human 293 cells.

Specification

• Description: This gene encodes the alpha chain of the interleukin-4 receptor, a type I transmembrane protein that can bind interleukin 4 and interleukin 13 to regulate IgE production. The encoded protein also can bind interleukin 4 to promote differentiation of Th2 cells. A soluble form of the encoded protein can be produced by an alternate splice variant or by proteolysis of the membrane-bound protein, and this soluble form can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells. Allelic variations in this gene have been associated with atopy, a condition that can manifest itself as allergic rhinitis, sinusitus, asthma, or eczema. Two transcript variants encoding different isoforms, a membrane-bound and a soluble form, have been found for this gene.
• Conjugation: Fc
• Biological activity: The ED50 of IL4R - Fc Chimera is typically 45-60 ng/ml as measured by its ability to neutralize IL-4 mediated proliferation of the human growth factor dependent TF-1 cell line.
• Form: Lyophilised:It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial.
• Purity: >95% by SDS-PAGE
• Storage buffer: Preservative: NoneConstituents: 10% Trehalose, 1% Human serum albumin, PBS
