    0.1 µg/mL
    Recombinant Mouse ST2/IL-33 R Fc Chimera (Catalog # 1004-MR)
  • Neutralization
    Measured by its ability to neutralize IL‑33-induced proliferation in the D10.G4.1 mouse helper T cell line. Schmitz, J. et al. (2005) Immunity 23:479. The Neutralization Dose (ND50) is typically 1-6 μg/mL in the presence of 1 ng/mL Recombinant Human IL‑33 and Hamster Anti-Mouse CD3 epsilon Monoclonal Antibody.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
Cell Proliferation Induced by IL‑33 and Neutralization by Mouse ST2/IL-33 R Antibody. Recombinant Human IL‑33 (Catalog # 3625-IL) induces proliferation in the D10.G4.1 mouse helper T cell line in the presence of Hamster Anti-Mouse CD3 epsilon Monoclonal Antibody (Catalog # MAB484) in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Under these conditions, proliferation elicited by IL‑33 is neutralized (green line) by increasing concentrations of Goat Anti-Mouse ST2/IL-33 R Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1004). The ND50 is typically
1-6 μg/mL.

Background: ST2/IL-33 R
ST2, also known as IL-1 R4 and T1, is an Interleukin-1 receptor family glycoprotein that contributes to Th2 immune responses. Mouse ST2 consists of a 306 amino acid (aa) extracellular domain (ECD) with three Ig-like domains, a 23 aa transmembrane segment, and a 212 aa cytoplasmic domain with an intracellular TIR domain. Alternate splicing of the 120 kDa mouse ST2 generates a soluble 60 kDa isoform that lacks the transmembrane and cytoplasmic regions. Within the ECD, mouse ST2 shares 68% and 81% aa sequence identity with human and rat ST2, respectively. ST2 is expressed on the surface of mast cells, activated Th2 cells, macrophages, and cardiac myocytes. It binds IL-33, a cytokine that is upregulated by inflammation or mechanical strain in smooth muscle cells, airway epithelia, keratinocytes, and cardiac fibroblasts. IL-33 binding induces the association of ST2 with IL-1R AcP, a shared signaling subunit that also associates with IL-1 RI and IL‑1 R rp2. In macrophages, ST2 interferes with signaling from IL-1 RI and TLR4 by sequestering the adaptor proteins MyD88 and Mal. In addition to its role in promoting mast cell and Th2 dependent inflammation, ST2 activation enhances antigen induced hypernociception and protects from atherosclerosis and cardiac hypertrophy. The soluble ST2 isoform is released by activated Th2 cells and strained cardiac myocytes and is elevated in the serum in allergic asthma. Soluble ST2 functions as a decoy receptor that blocks IL-33’s ability to signal through transmembrane ST2.
