Human Interleukin-11 Recombinant

IL-11 is secreted by bone marrow stromal cells (fibroblasts) and is produced also by a number of mesenchymal cells. The IL-11 receptor (alpha chain) utilizes gp130 as its signal transducer, which is also a component of other cytokine receptors. The alpha chain of the IL-11 receptor has been identified independently as Etl2. IL-11 promotes primary and secondary immune responsesin vitroandin vivoand modulates antigen-specific antibody reactions. IL-11 promotes the proliferation of IL-6 dependent plasmacytoma cell lines in the presence of neutralizing IL-6 antibodies. IL-11 also stimulates the T-cell dependent development of IgG-secreting B-cells in spleen cell cultures. IL-11 inhibits the differentiation of pre- adipocytes. It induces the synthesis of some acute phase proteins by hepatocytes.

A quick spin of the vial followed by reconstitution in distilled water to concentration not less than 0.1 mg/ml. This can then be diluted into other buffers.

The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
