After reconstitution, the protein solution is stable at -20 degree C for 3 months, at 2-8 degree C for up to 1 week.
Background: Interleukin 11 (IL-11) is a member of a family of human growth factors that includes human growth hormone,granulocyte colony-stimulating factor, and other growth factors. IL-11 is a thrombopoietic growth factor thatdirectly stimulates the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells andinduces megakaryocyte maturation resulting in increased platelet production. It also promotes theproliferation of hepatocytes in response to liver damage. Binding to its receptor formed by IL6ST and eitherIL11RA1 or IL11RA2, It activates a signaling cascade that promotes cell proliferation. The signaling leads to theactivation of intracellular protein kinases and the phosphorylation of STAT3.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a member of the gp130 family of cytokines. These cytokines drive the assembly of multisubunit receptor complexes, all of which contain at least one molecule of the transmembrane signaling receptor IL6ST (gp130). This cytokine is shown to stimulate the T-cell-dependent development of immunoglobulin-producing B cells. It is also found to support the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jun 2012]
