IL-13R alpha 1 Antibody (419718) [Unconjugated]

Western blot shows lysates of human heart tissue and human skeletal muscle tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human IL-13 Ra1 Monoclonal Antibody (Catalog # MAB1462) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for IL-13 Ra1 at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Human peripheral blood granulocytes were stained with (A) MouseAnti-Human Siglec-3/CD33 APC-conjugated Monoclonal Antibody (Catalog # FAB1137A) and (B) Mouse Anti-Human IL‑13 R alpha 1 Monoclonal Antibody (Catalog # MAB1462, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')2 Secondary Antibody (Catalog # F0102B).

Background

Two type 1 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 human IL-13 R alpha 1 was originally cloned based on sequence homology to the mouse IL-13 R alpha 1. The IL-13 R alpha 1 cDNA encodes a 427 amino acid (aa) precursor protein with a putative 21 aa signal peptide, a 324 aa extracellular domain, a 23 aa transmembrane region and a 59 aa cytoplasmic tail. Human and mouse IL-13 R alpha 1 share 76% aa sequence identity. The extracellular domain of IL-13 R alpha 1 is also closely related to that of IL-13 R alpha 2. IL‑13 R alpha 1 has been shown to combine with the IL-4 R alpha to form a high-affinity receptor complex capable of transducing an IL-13-dependent proliferative signal. The role of IL-13 R alpha 2 in IL-13 signaling remains to be elucidated.
