IL-21R Protein, Human (HEK293, Fc)

IL-21R protein, a receptor for interleukin-21, forms a heterodimer with the common gamma subunit and associates with Janus kinase 1 (JAK1). These interactions are pivotal for transducing the cellular responses initiated by interleukin-21, regulating immune processes and inflammatory pathways. IL-21R Protein, Human (HEK293, Fc) is the recombinant human-derived IL-21R protein, expressed by HEK293 , with C-hFc labeled tag.

The IL-21R protein serves as a receptor for interleukin-21. It forms a heterodimer with the common gamma subunit and associates with Janus kinase 1 (JAK1). Through this interaction, the receptor facilitates the signaling cascade initiated by interleukin-21, a cytokine with diverse immunoregulatory functions. The formation of the IL-21R heterodimer and its association with JAK1 are pivotal steps in transducing the cellular responses triggered by interleukin-21, contributing to the regulation of immune processes and inflammatory pathways.

Measured by its binding ability in a functional ELISA. When immobilized Human IL-21 at 2 μg/mL (100μL/Well), can bind Human IL-21R with the EC₅₀ of <62.4 ng/mL.

Greater than 95% as determined by Tris-Bis PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 5% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
