IL-11 is a multifunctional cytokine produced by stromal cells such as fibroblasts, epithelial cells and osteoclasts. It is expressed in a wide variety of tissues including thymus, lung, bone, connective tissue and central nervous system. IL-11 plays an important regulatory role in hematopoiesis by stimulating growth of myeloid, erythroid and megakaryocyte progenitor cells. It also regulates bone metabolism, inhibits production of proinflammatory cytokines and protects against gastromucosal injury. Recombinant Murine IL-11 is a 19.1 kDa protein consisting of 179 amino acid residues.
Mouse Il11 expressed in E.coli
CAT# CSC-CTK0689-10 (10 μg); CAT# CSC-CTK0689-50 (50 μg)
Greater than 98% as determined by SDS-PAGE and HPLC analysis.
The ED50 as determined by the dose-dependent stimulation of the proliferation of murine T11 cells is ≤ 2.0 ng/ml, corresponding to a specific activity of Greater than 5 x 10^5 units/mg.
Less than 1 EU/μg.
Lyophilized from a sterile-filtered solution with no additives.
Please centrifuge product before opening vial. The lyophilized protein should be reconstituted with distilled, sterile water to a concentration of 0.1-1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
