Product Description	Recombinant Human IL-4 R alpha/CD124 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gly24-His232.
Product Background	Interleukin 4 Receptor alpha (IL-4 Ra), also known as CD124 and BSF receptor, is a widely expressed 140 kDa transmembrane glycoprotein in the class I cytokine receptor family.The effects of IL-4 are mediated after binding to high affinity receptor complexes present on hematopoietic as well as non-hematopoietic cells.
Product Category	Recombinant Protein

Target	IL-4 R alpha/CD124
Synonyms	CD124; IL-4 R alpha; IL-4R subunit alpha; IL4R; IL-4Ra; IL4RACD124
Gene/Protein ID	P24394-1
Species	Human
Exact Sequence	Gly24-His232
Molecular Weight	The protein has a predicted MW of 24.7 kDa. Due to glycosylation, the protein migrates to 45-70 kDa based on Tris-Bis PAGE result.
Activity	Immobilized Human IL-4 R alpha, His Tag at 1ug/ml (100ul/Well). Dose response curve for Biotinylated Human IL-4, His Tag with the EC50 of 6.1ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-His
Express System	HEK293
Purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
