Human IL-11 Protein, His Tag

  • Synonym
    IL-11,Interleukin-11,AGIF,Oprelvekin,IL11
  • Source
    Human IL-11, His Tag (IL1-H5243) is expressed from human 293 cells (HEK293). It contains AA Pro 22 - Leu 199 (Accession # P20809-1).
    Predicted N-terminus: His
  • Molecular Characterization
    Online(Pro 22 - Leu 199) P20809-1

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 21.0 kDa. The protein migrates as 22-24 kDa and 25-27 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

  • Background
    Interleukin-11 (IL-11) is a pleiotropic cytokine that stimulates megakaryocytopoiesis, resulting in increased production of platelets, as well as activating osteoclasts, inhibiting epithelial cell proliferation and apoptosis, and inhibiting macrophage mediator production. These functions may be particularly important in mediating the hematopoietic, osseous and mucosal protective effects of IL-11. The cytokine also possesses anti-inflammatory activity, and has been proposed as a therapeutic agent in the treatment of chronic inflammatory diseases, such as Crohn's disease and rheumatoid arthritis. Although IL-11 was initially believed to be restricted to mammals, subsequent studies demonstrated it to be expressed in fish. Despite close similarity in gene structure and conservation of key amino acids between fish and mammalian IL-11, they share relatively low overall amino acid identity and may not necessarily be functionally analogous.
