Human IL-4 R alpha/CD124 Protein (ILA-HM14R)
|Recombinant Human IL-4 R alpha/CD124 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gly24-His232.
|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.

|CD124; IL-4 R alpha; IL-4R subunit alpha; IL4R; IL-4Ra; IL4RACD124
|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.
|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.
|> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
|Less than 1EU per ug by the LAL method.
|Shipped at ambient temperature.
|Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
|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.
