    Human IL-33, Tag Free (IL3-H4112) is expressed from E.coli cells. It contains AA Ser 112 - Thr 270 (Accession # AAH47085).
    Predicted N-terminus: Met
  • Molecular Characterization
    IL-33(Ser 112 - Thr 270) AAH47085

    This protein carries no "tag".

    The protein has a calculated MW of 18.2 kDa. The protein migrates as 18-20 kDa under reducing (R) condition (SDS-PAGE).

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

    >97% 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.
