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), and IL-11 can inhibit Th1 responses and inhibits the production of Th1 cytokines such as IL-12 and shifts 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, 180 amino acids Val20-Leu199 (Accession# P20809.1) was expressed in 293E.
- Molecular Mass
- The 180 amino acid recombinant protein has a predicted molecular mass of approximately 19.3 kD. The DTT-reduced and non reduced proteins migrate at approximately 19.3 kD by SDS-PAGE. The N-terminal amino acid is Valine.
- Purity
- >98%, as determined by Coomassie stained SDS-PAGE.
- Formulation
- 0.22 µm filtered protein solution is in PBS.
- Endotoxin Level
- Less than 0.01 ng per µg cytokine as determined by the LAL method.
- Concentration
- 10 and 25 µg sizes are bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
- Storage & Handling
- Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
- Activity
- The ED50 is 4-12 ng/ml, corresponding to a specific activity 8.3 x 104 - 2.5 x 105 units/mg, as determined by a dose-dependent stimulation of 7TD1 cells proliferation.

- Application Notes
-
BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue-ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are verified in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee.
