Applications

Recommended Concentration
Sample
Western Blot
1 µg/mL
Recombinant Human IL‑11 (Catalog # 218-IL)
Neutralization
Measured by its ability to neutralize IL‑11-induced proliferation in the T11 mouse plasmacytoma cell line. Nordan, R. P. and M. Potter (1986) Science 233:566. The Neutralization Dose (ND50) is typically 10-20 µg/mL in the presence of 1 ng/mL Recombinant Human 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 Human IL‑11 Antibody. Recombinant Human IL‑11 (Catalog # 218‑IL) stimulates proliferation in the T11 mouse plasmacytoma cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL‑11 (1 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human IL‑11 Polyclonal Antibody (Catalog # AB‑218‑NA). The ND50 is typically 10‑20 µg/mL.

Background: IL-11

Interleukin 11 is a pleiotropic cytokine that was originally detected in the conditioned medium of an IL-1 alpha -stimulated primate bone marrow stromal cell line (PU-34) as a mitogen for the IL-6-responsive murine plasmacytoma cell line T1165. IL-11 was also independently discovered as an adipogenesis inhibitory factor (AGIF). The human IL-11 cDNA encodes a 199 amino acid residue precursor polypeptide with a 21 amino acid residue hydrophobic signal that is processed proteolytically to generate the 178 amino acid residue mature protein. IL-11 contains no cysteine residues or potential glycosylation sites.

IL-11 has multiple effects on both hematopoietic and nonhematopoietic cells. Many of the biological effects described for IL-11 overlap those for IL-6. In vitro, IL-11 can synergize with IL-3, IL-4 and SCF to shorten the G0 period of early hematopoietic progenitors. IL-11 also enhances the IL-3-dependent megakaryocyte colony formation. IL-11 has been found to stimulate the T cell dependent development of specific immunoglobulin-secreting B cell. IL-11, in the presence of IL-3 or SCF, has also been shown to stimulate erythropoiesis. Among nonhematopoietic cell populations, IL-11, like IL-6 and LIF, can stimulate the synthesis of hepatic acute-phase proteins. Consistent with the in vitro functions of IL‑11, in vivo administration of rhIL-11 in normal mice was found to enhance the generation of Ig producing cells and platelets, and to increase the cycling rates of bone marrow-derived CFU-GM, BFU-E, and CFU-GEMM progenitors.

IL-11 exerts its biological activities through binding to a specific high-affinity receptor having an apparent molecular mass of 150 kDa. Although the IL-11 binding subunit of the receptor complex has not yet been cloned, evidence suggests that, similar to IL-6, leukemia inhibitory factor, oncostatin M, and ciliary neurotrophic factor, IL-11 utilizes the IL-6 signal transducer, gp130, for signal transduction.
