Scientific Data Images for Mouse IL-21R Antibody

Detection of IL-21 R antibody in A20 Mouse Cell Line antibody by Flow Cytometry.

Detection of IL‑21 R in A20 Mouse Cell Line by Flow Cytometry.

A20 mouse B cell lymphoma cell line was stained with Goat Anti-Mouse IL-21 R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF596, filled histogram) or isotype control antibody (Catalog # AB-108-C, open histogram), followed by Phycoerythrin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0107).

IL-10 in Mouse Splenocytes.

IL-10 was detected in immersion fixed mouse splenocytes using Goat Anti-Mouse/Rat IL-10 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF519) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells<.>

Background: IL-21R

The interleukin-21 (IL-21) and its receptor appear to play important roles in the regulation of the immune system. 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 R is a 529 amino acid (aa) residue protein with a 19 aa signal peptide, a 217 aa extracellular domain, an 18 aa transmembrane domain, and a 275 aa cytoplasmic domain. Mouse and human IL-21 R share 62% aa identity. IL-21 R is expressed on lymphoid tissues, peripheral B cells, and cell lines of T, B and natural killer lineage. Although not fully elucidated, the IL-2 R gamma ( gammac) chain appears to play a role in IL-21 R signaling. The IL-21/IL-21 R interaction appears to play important roles in B and T cell proliferation after antigen stimulation and natural killer cell maturation.
