IL-13R alpha 2 Antibody [Unconjugated]

IL‑13 R alpha 2 was detected in perfusion fixed frozen sections of mouse thymus using Goat Anti-Mouse IL‑13 R alpha 2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF539) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in lymphocytes. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

IL‑13 R alpha 2 was detected in immersion fixed mouse splenocytes using Mouse IL‑13 R alpha 2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF539) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

Background

Two type1 membrane proteins belonging to the hemopoietin receptor family have been cloned and shown to bind IL-13 with differing affinities. The lower affinity IL-13 binding protein, previously designated IL-13 R alpha, IL-13 R alpha ' or NR4, is now referred to as IL-13 R alpha 1. The high affinity IL-13 binding protein, previously also designated IL-13 R or IL-13 R alpha ', is now referred to as IL-13 R alpha 2.

The mouse IL-13 R alpha 2 cDNA encodes a 383 amino acid (aa) residue precursor protein with a putative 21 aa residue signal peptide, a 313 residue extracellular domain, a 22 aa residue transmembrane region, and a 27 aa residue cytoplasmic tail. Human and mouse IL-13 R alpha 2 share 59% aa sequence identity. The extracellular domain of IL-13 R alpha 2 is also closely related to that of IL-13 R alpha 1. However, the cytoplasmic domain of IL-13 R alpha 2 lacks the box 1 and box 2 signaling motif and is much shorter than that of IL-13 R alpha 1, suggesting that the two receptors are functionally distinct. IL-13 R alpha 1 has been shown to combine with IL-4 R alpha to form a high-affinity receptor complex capable of transducing both an IL-4-dependent and an IL-13-dependent proliferative signal. The role of IL-13 R alpha 2 in IL-13 signaling remains to be elucidated. The amino-terminal 27 amino acid residues of mouse IL-13 R alpha 2 are identical to that of a soluble mouse IL-13 binding protein purified from mouse serum and urine. Recombinant mouse IL-13 R alpha /Fc chimera has been shown to bind IL-13 with high affinity and is a potent IL-13 antagonist.
