IL-11, a member of the IL-6 family of cytokines, exerts a wide range of biological effects on various cell types including hematopoietic cells, hepatocytes, adipocytes, neurons, and osteoblasts. IL-11 works synergistically with other growth factors including SCF, IL-4, IL-3, IL-7, IL-12, IL-13, and GM-CSF to stimulate the proliferation of cells from several hematopoietic lineages. Binding of IL-11 to IL-11 receptor (IL-11R) induces membrane bound gp130 homodimerization and triggers STAT3 phosphorylation by JAK. IL-11 shares the common receptor subunit gp130 with IL-6, IL-27, LIF, OSM, CNTF, CT-1, CLC, and NP. Female mice deficient in IL-11R revealed an important role for IL-11 in embryonic implantation. In addition, IL-11 shows anti-inflammatory activity in models of inflammatory bowel disease, chemotherapy induced oral mucositis, and inflammatory arthritis. IL-11 and IL-13 are highly expressed in asthmatic airways (Th2 response). IL-11 can inhibit Th1 responses and the production of Th1 cytokines such as IL-12, shifting inflammation in Th2 direction. Elevated IL-11 expression is associated with tumor grade and invasion in gastric cancer. Recombinant human IL-11 has been clinically approved to improve platelet recovery after chemotherapy-induced thrombocytopenia.
Product Details
- Source
- Human IL-11, amino acids Pro22-Leu199 (Accession# P20809.1), was expressed in E. coli.
- Molecular Mass
- The 179 amino acid N-terminal methionylated recombinant protein has a prodicted molecular mass of 19.1 kD. The predicted N-terminal amino acid is Met.
- Purity
- >98%, as determined by Coomassie stained SDS-PAGE and HPLC analysis.
- Formulation
- Lyophilized, carrier-free.
- Endotoxin Level
- Less than 0.1 ng per µg of protein.
- Storage & Handling
- Unopened vial can be stored at -20°C or -70°C. For maximum results, quick spin vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. It is recommended to further dilute in a buffer, such as 5% Trehalose, and store working aliquots at -20°C to -80°C. Avoid repeated freeze/thaw cycles.
- Activity
- ED50 is ≤ 2.0 ng/ml, corresponding to a specific activity of ≥ 5.0 x 105 units/mg as determined by the dose-dependent stimulation of the proliferation of murine T11 cells.

Antigen Details
- Structure
- Cytokine
- Distribution
- IL-11 can be secreted by various cell types including epithelial, endothelial, keratinocytes, stromal, neuronal, fibroblasts, osteoclasts, and bone marrow stromal cells.
- Function
- IL-11, a multifunctional cytokine, plays important roles in hemopoiesis, thrombopoiesis, megakaryocytopoiesis, and bone resorption; It regulates macrophage differentiation and confers mucosal protection after chemotherapy and radiation therapy. IL-11 expression can also be up-regulated by oncogenic Ras or respiratory virus infections. IL-11 and IL-11Rα are induced by IL-13.
- Interaction
- Hematopoietic cells, hepatocytes, adipocytes, neurons, osteoblasts, fibroblasts, and gastrointestinal epithelial cells.
- Ligand/Receptor
- Membrane bound or soluble IL-11Rα heterodimerize with gp130β.
- Cell Type
- Hematopoietic stem and progenitors
- Biology Area
- Cell Biology, Cell Motility/Cytoskeleton/Structure, Immunology, Stem Cells
