  • Synonym
    IL18BP,IL18BPa,Tadekinig-alfa
  • Source
    Human IL-18BP, Fc Tag(ILP-H5253) is expressed from human 293 cells (HEK293). It contains AA Thr 31 - Gly 194 (Accession # NP_001138529 ).
    Predicted N-terminus: Thr 31
  • Molecular Characterization
    IL-18BP Structure

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 44.3 kDa. The protein migrates as 56-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Background
    Interleukin-18-binding protein (IL18BP) is also known as Tadekinig-alfa, IL18BPa, which functions as an IL18 inhibitor. IL18BP is a secreted protein which contains one Ig-like C2-type (immunoglobulin-like) domain. IL18BP does not have a transmembrane domain and hence is not anchored to the cell membrane. IL18BP is strongly expressed in heart, lung, placenta and spleen. Isoform A of IL18BP binds to IL-18 and inhibits its activity. IL18BP also functions as an inhibitor of the early TH1 cytokine response. IL18BP suppresses the production of IFN-gamma resulting in reduced T-helper type 1 immune responses.
