More Information
Product Details
Synonyms Interleukin-21 Receptor; CD360; NILR
Product Type Protein
Source/Host CHO cells

The extracellular domain of mouse IL-21R (aa 20-234) is fused to the N-terminus of the Fc region of a mutant mouse IgG2a.

Crossreactivity Mouse
Biological Activity

Shows the biological function of the IL-21R moiety and exerts a prolonged circulating half-life caused by the modified Fc domain.

MW ~50-100kDa
Purity ≥98% (SDS-PAGE)
Endotoxin Content <1EU/mg protein (LAL test; Lonza).
Reconstitution Reconstitute at 100μg/ml in sterile PBS.
Formulation Lyophilized from 0.2μm-filtered solution in PBS.
Protein Negative Control

Fc (mouse) IgG2a Control (rec.) (non-lytic)

Other Product Data

Non-lytic: Acts as a long lasting fusion protein which only binds to the receptor. Mutations to the complement (C1q) and FcgR I binding sites of the IgGs Fc fragment render the fusion proteins incapable of antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC).

Interleukin-21 receptor (IL-21R) is a type I transmembrane glycoprotein within the class I cytokine receptor family, type 4 subfamily. Complex formation between IL-21R and the common γ chain (γc) is required for signaling. IL-21R is expressed mainly on B cells (highest on mature, activated, follicular and germinal center B cells), NK cells and activated T cells, but is also found on dendritic cells, alternatively activated macrophages, intestinal lamina propria fibroblasts and epithelial cells and keratinocytes. B cell IL-21R engagement induces Blimp1 (which mediates plasma cell differentiation) and is important for memory responses. IL-21R engagement on mouse NK cells enhances their cytotoxic activity and IFN-γ production. IL-21R engagement on CD8+ T cells aids control of viral infection and tumor growth; IL-21R is also necessary for sufficient numbers of regulatory T cells to combat chronic inflammation. IL-21R expression is often upregulated in allergic skin inflammation, systemic lupus erythematosus and diffuse large B cell lymphoma (DLBCL).
