Recombinant Human IL11 (E. coli)

Cat. No.
Cat. No. Z100425
Name Recombinant Human IL11 (E. coli)
Description IL11 is secreted by bone marrow stromal cells (fibroblasts) and is produced also by a number of mesenchymal cells. The IL11 receptor (alpha chain) utilizes gp130 as its signal transducer, which is also a component of other cytokine receptors. The alpha chain of the IL11 receptor has been identified independently as Etl2. IL-1 promotes primary and secondary immune responses in vitro and in vivo and modulates antigen-specific antibody reactions. IL11 promotes the proliferation of IL6 dependent plasmacytoma cell lines in the presence of neutralizing IL6 antibodies. IL11 also stimulates the T cell dependent development of IgG-secreting B cells in spleen cell cultures. IL11 inhibits the differentiation of pre-adipocytes. It induces the synthesis of some acute phase proteins by hepatocytes.

Formulation Lyophilized from a 0.2 μm filtered solution in tris buffer and NaCl.
Function The ED(50) was determined by the dose-dependent stimulation of the proliferation of murine T11 cells is ≤ 1.0 ng/ml, corresponding to a specific activity of ≥ 1.0 x 10^6 units/mg.
Reconstitution A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage For research use only. Not for diagnostic or therapeutic use.
