Human IL37b / IL1F7b Protein

  • Synonym
    IL1F7,IL37,FIL1Z,IL1H4,IL1RP1
  • Source
    Human IL-37b, His Tag (ILB-H5141) is expressed from E.coli cells. It contains AA Val 46 - Asp 218 (Accession # AAH20637).
    Predicted N-terminus: Met
  • Molecular Characterization
    IL-37(Val 46 - Asp 218) AAH20637

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

    The protein has a calculated MW of 20.3 kDa. The protein migrates as 20.3 kDa under reducing (R) condition (SDS-PAGE).

  • 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 PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    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.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
Human IL-37b, His Tag (Cat. No. ILB-H5141) SDS-PAGE gel

Human IL-37b, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

  • Background
    Interleukin-1 family member 7 (IL1F7b) ,a member of the IL-1 family, is aslo known as interleukin-37, interleukin-1 homolog 4 (IL-1H4), interleukin-1 zeta (IL-1 zeta) and interleukin-1-related protein, which can interact with SMAD3 and bind to IL18R1, but not to IL1R1, with lower affinity than IL18. IL1F7b is a suppressor of innate inflammatory and immune responses involved in curbing excessive inflammation. This function requires SMAD3. Therefore,IL1F7b can suppress, or reduce, proinflammatory cytokine production, including IL1A and IL6, as well as CCL12, CSF1, CSF2, CXCL13, IL1B, IL23A and IL1RN, but spare anti-inflammatory cytokines. Furthermore,IL1F7b can also inhibit dendritic cell activation.
