Purity > 85% as determined by SDS-PAGE. MW: 25.4kDa. Full Length of Mature Protein: 22-199aa. N-terminal 6xHis-tagged. Macaca fascicularis (Crab-eating macaque) (Cynomolgus monkey). Cytokine that stimulates the proliferation of hematopoietic stem cells and megakaryocyte progenitor cells and induces megakaryocyte maturation resulting in increased platelet production. Also promotes the proliferation of hepatocytes in response to liver damage. Binding to its receptor formed by IL6ST and either IL11RA1 or IL11RA2 activates a signaling cascade that promotes cell proliferation. Signaling leads to the activation of intracellular protein kinases and the phosphorylation of STAT3.
