Catalog# CC81 Source HEK293 Description Recombinant Human Interleukin-21 receptor/IL-21R is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Cys20-Pro236) of Human IL-21R fused with a polyhistidine tag at the C-terminus. Names Interleukin-21 receptor is also known as IL-21 receptor, IL-21R, CD360. Accession # Q9HBE5 Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl,pH7.4 Shipping The product is shipped at ambient temperature. Reconstitution Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in 1X PBS.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Storage Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.Purity Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. Endotoxin Less than 0.1 ng/µg (1 IEU/µg).

In humans, it is encoded by the IL21R gene. It belongs to the type I cytokine receptor family. Type 4 subfamily contains 2 fibronectin type-III domains. Interleukin-21 receptor is selectively expressed in lymphoid tissues and highly expressed in thymus and spleen. IL-21 is produced by CD4+ T cells in response to antigenic stimulation. Its action enhances antigen-specific responses of immune cells. The biological effects of IL-21 include induction of differentiation of T-cells-stimulated B-cells into plasma cells and memory B-cells. It also promotes the anti-tumor activity of CD8+ T-cells and NK cells.
