Recombinant Human IL21R protein, His-tagged

Specification :
| Description : Interleukin-21 receptor (IL21R) is also known as CD antigen CD360, Novel interleukin receptor (NILR), is a receptor for interleukin-21 and belongs to the type I cytokine receptor family or type 4 subfamily. IL21R contains two fibronectin type-III domains. IL21R is selectively expressed in lymphoid tissues and most highly expressed in thymus and spleen. IL21R transduces the growth promoting signal of IL21, and is important for the proliferation and differentiation of T cells, B cells, and natural killer (NK) cells. | Source : HEK293 | Species : Human | Tag : His | Predicted N Terminal : Cys20 | Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose. | Molecular Mass : The protein has a calculated MW of 25.8 kDa. The protein migrates as 36-46 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. | Protein length : Cys20-Pro236 | Endotoxin : Less than 1.0 EU per μg by the LAL method. | Purity : >92% as determined by SDS-PAGE. | Storage : For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.Please avoid repeated freeze-thaw cycles.This product is stable after storage at:-20 to -70 centigrade for 12 months in lyophilized state;-70 centigrade for 3 months under sterile conditions after reconstitution. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
