  • Source
    Human IL-3 R alpha, His Tag (ILA-H52H6) is expressed from human 293 cells (HEK293). It contains AA Thr 19 - Arg 305  (Accession # P26951-1).
    Predicted N-terminus: Thr 19
  • Molecular Characterization
    Online(Thr 19 - Arg 305 ) P26951-1

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

    The protein has a calculated MW of 35.0 kDa. The protein migrates as 55-65 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.

    >90% as determined by SEC-MALS.

  • Formulation

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

  • Background
    Interleukin 3 receptor alpha (low affinity) (IL3RA), also known as CD123 (Cluster of Differentiation 123) is a 70-kD glycoprotein member of the hematopoietin receptor superfamily. This protein associates with a beta subunit common to the receptors for IL-5 and granulocyte-macrophage colony-stimulating factor (GM-CSF) to form a high-affinity receptor for IL-3. The interleukin-3 receptor α chain (CD123) has been identified as a potential immunotherapeutic target because it is overexpressed in AML compared with normal hematopoietic stem cells.
