Interleukin-21 (IL-21) and its receptor appear to play important roles in the regulation of the immune system. IL-21 is most related to IL-2, IL-4, and IL-15. IL-21 R, also called NILR (novel interleukin receptor), is a type I cytokine receptor with 4 conserved cysteine residues and an extracellular WSXWS motif. It is most closely related to IL-2 R beta and IL-4 R alpha. Mouse IL-21 is a 146 amino acid (aa) residue protein with a 24 aa signal peptide. Mouse and human IL-21 share 57% amino acid identity. IL‑21 is expressed by activated T cells. Although not fully elucidated, the IL-2 R gamma ( gamma c) chain appears to play a role in IL-21 R signaling. The IL-21/IL-21 R interaction appear to play important roles in B and T cell proliferation after antigen stimulation and NK cell maturation.

Scientific Data Images for Mouse IL-21 Antibody [Biotin]
Mouse IL-21 ELISA Standard Curve
Recombinant Mouse IL‑21 (Catalog # 594-ML) was serially diluted and captured by Goat Anti-Mouse IL‑21 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF594) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Mouse IL‑21 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF594) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998)Applications for Mouse IL-21 Antibody [Biotin]
