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.

Recombinant Human IL-21 R, His Tag (ILR-H5226) is expressed from human 293 cells (HEK293). It contains AA Cys 20 - Pro 236 (Accession # Q9HBE5-1).
Predicted N-terminus: Cys 20

Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.9 kDa. The protein migrates as 37-47 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Less than 1.0 EU per μg by the LAL method.

>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

See Certificate of Analysis for reconstitution instructions and specific concentrations.
