Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.


Recommended Concentration
Western Blot
0.1 µg/mL
Recombinant Mouse IL‑11 R alpha Fc Chimera (Catalog # 490-IR)
Measured by its ability to neutralize IL‑11-induced proliferation in the T11 mouse plasmacytoma cell line. Nordan, R. P. et al. (1987) J. Immunol. 139:813. The Neutralization Dose (ND50) is typically 1-6 µg/mL in the presence of 1 ng/mL Recombinant Mouse IL‑11.

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.

Cell Proliferation Induced by IL‑11 and Neutralization by Mouse IL‑11 R alpha Antibody. Recombinant Mouse IL-11 (Catalog # 418-ML) stimulates proliferation in the T11 mouse plasmacytoma cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL-11 (1 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse IL-11 Ra Antigen Affinity-purified Polyclonal Antibody (Catalog # AF490). The ND50 is typically 1-6 µg/mL.

Background: IL-11 R alpha

Mouse interleukin 11 receptor alpha (IL-11 R alpha ), originally designated NR1, is a member of the hematopoietic cytokine receptor family that was cloned on the basis of its conserved WSXWS motif. IL-11 R alpha cDNA encodes a 432 amino acid (aa) residue precursor type I membrane protein with a 23 aa residue signal peptide, a 344 aa residue extracellular domain containing two potential glycosylation sites, a 26 aa residue transmembrane region and a short (39 aa residue) cytoplasmic domain. In comparison with other hematopoietic cytokine receptors, the extracellular domain of IL-11 R alpha is closely related to that of IL-6 R alpha, CNTF R alpha and the p40 subunit of IL‑12, exhibiting 24%, 22% and 16% amino acid sequence identity, respectively. By itself, IL-11 R alpha binds IL-11 with low affinity. IL-11 R alpha, together with gp130, forms a functional high-affinity receptor complex for IL-11. The expression of IL-11 R alpha has been detected in all adult tissues examined (lung, stomach, intestine), during embryonic development and in totipotent and differentiating embryonic stem cells. Recombinant soluble IL-11 R alpha has been shown to mediate IL-11 responsiveness in cells expressing the gp130 molecule. In cells expressing transmembrane IL-11 R alpha and gp130, soluble IL-11 R alpha has been shown to act as an IL-11 antagonist.
