Human IL-18 R1 / CD218a Protein, Fc Tag

  • Synonym
    IL18R1,IL1RRP,CD218a,IL18Ra
  • Source
    Human IL-18 R1, Fc Tag(IL1-H5259) is expressed from human 293 cells (HEK293). It contains AA Ala 19 - Arg 329 (Accession # AAH69575).
    Predicted N-terminus: Ala 19
  • Molecular Characterization
    IL-18 R1 Structure

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

    The protein has a calculated MW of 62.4 kDa. The protein migrates as 80-95 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.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
IL-18 R1 SDS-PAGE

Human IL-18 R1, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.

Bioactivity-SPR
 IL-18 R1 SPR

Human IL-18 R1, Fc Tag (Cat. No. IL1-H5259) captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind Human IL-18, Tag Free with an affinity constant of 0.409 μM as determined in a SPR assay (Biacore 8K) (Routinely tested).

  • Background
    Interleukin-18 receptor 1 (IL18R1) is also known as CD218 antigen-like family member A (CD218a), IL1 receptor-related protein (IL-1Rrp or IL1R-rp), CDw218a, IL18Ra, IL1RRP, which belongs to the interleukin-1 receptor family. IL18R1 contains three Ig-like C2-type (immunoglobulin-like) domains and one TIR domain. IL18R1 is receptor for interleukin 18 (IL-18). IL18R1 binds to the agonist leads to the activation of NF-kappa-B, but does not bind IL1A/interleukin-1 alpha or IL1B/interleukin-1 beta.
