Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human sIL-4 Receptor alpha. Anti-Human sIL-4 Receptor alpha-specific antibody was purified by affinity chromatography employing an immobilized Human sIL-4 Receptor alpha matrix.

Sandwich ELISA: To detect Human sIL-4 Receptor alpha by sandwich ELISA (using 100 µL/well), a concentration of 0.5-2.0 µg/mL of this antibody is required. This antigen affinity purified antibody, in conjunction with PeproTech Biotinylated Anti-Human sIL-4 Receptor alpha (500-P325BT) as a detection antibody, allows the detection of at least 2000-4000 pg/mL of Recombinant Human sIL-4 Receptor alpha.

Western Blot: To detect Human sIL-4 Receptor alpha by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 µg/mL. When used in conjunction with compatible secondary reagents, the detection limit for Recombinant Human sIL-4 Receptor alpha is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions.

Target Information

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.
