Species: Human Expressing host: HEK293 cells Description: Recombinant Human IL-4RA/CD124 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Gly24-His232) of human IL4R/CD124 (Accession #NP_000409.1) fused with a 6His tag at the C-terminus. Tag: C-His Purity: > 87% by SDS-PAGE. Endotoxin: Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized recombinant human IL4R at 2 g/mL (100 L/well) can bind recombinant human IL4. The ED50of recombinant human IL4R is 2-4 ng/mL. preparation: Lyophilized from a 0.22 m filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. Storage Store the lyophilized protein at -20C to -80 C for long term.
After reconstitution, the protein solution is stable at -20 C for 3 months, at 2-8 C for up to 1 week.Unopened freeze-dried powder,Store at -20 to -80 °C for twelve months
Redissolution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex 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.Redissolution:Store at -20 to -80 °C,avoid repeated freeze thaw cycles
Background Information : 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. GeneID 3566 Swiss Prot P24394 Alias: IL4R;CD124;IL-4RA;IL4RAMedChemExpress (MCE) recombinant proteins include: cytokines, enzymes, growth factors, hormones, receptors, transcription factors, antibody fragments, etc. They are often essential for supporting cell growth, stimulating cell signaling pathways, triggering or inhibiting cell differentiation; and are useful tools for elucidating protein structure and function, understanding disease onset and progression, and validating pharmaceutical targets. At MedChemExpress (MCE), we strive to provide products with only the highest quality.
