|Synonyms||Interleukin-4 receptor subunit alpha, IL-4 receptor subunit alpha, IL-4R subunit alpha, IL-4R-alpha, IL-4RA, CD124, IL-4-binding protein, IL4-BP, IL4R, IL4RA|
|Sequence||Met 1-His 232|
|Bio_Activity||1. Immobilized human IL4R-His at 10 μg/mL (100 μl/well) can bind biotinylated human IL4. The EC50 of biotinylated human IL4 is 20.8-48.5 ng/mL. 2. Measured by its ability to inhibit IL-4 dependent proliferation of TF-1 human erthroleukemic cells. The ED50 for this effect is 4-20 ng/ml in the presence of 2 ng/ml IL-4.|
|Purity||> 98 % as determined by reducing SDS-PAGE.|
|Endotoxin level||< 1.0 EU per μg of the protein as determined by the LAL method.|
|Storage||Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.|
|Shipping||This product is provided as lyophilized powder which is shipped with ice packs.|
|Formulation||Lyophilized from sterile PBS, pH 7.4
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
|Reconstitution||Please refer to the printed manual for detailed information.|
