Endotoxin:
< 0.1 EU/μg of the protein by LAL method.
Purity:
≥ 85 % as determined by SDS-PAGE.
Formulation:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
Bio-Activity:
Measured by its binding ability in a functional ELISA. Immobilized recombinant human IL4R at 2 μg/mL (100 μL/well) can bind recombinant human IL4. The ED 50 of recombinant human IL4R is 2-4 ng/mL.
Reconstitution:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
This protein is 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 proteolysis of the membrane-bound protein, and this soluble form can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells.
Recombinant Human IL-4R alpha/CD124 Protein was determined by SDS-PAGE under reducing conditions with Coomassie Blue.
Immobilized recombinant human IL4R at 2 μg/mL (100 μL/well) can bind recombinant human IL4. The ED50 of recombinant human IL4R is 2-4 ng/mL.
