Human IL-2 R beta / CD122 Protein, Fc Tag

  • Synonym
    IL2RB,RP5-1170K4.6,CD122,P70-75
  • Source
    Human IL-2 R beta, Fc Tag (ILB-H5253) is expressed from human 293 cells (HEK293). It contains AA Ala 27 - Asp 239 (Accession # NP_000869.1).
    Predicted N-terminus: Ala 27
  • Molecular Characterization
    Online(Ala 27 - Asp 239) NP_000869.1

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

    The protein has a calculated MW of 50.7 kDa. The protein migrates as 58-76 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >92% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • 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 was 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.

  • Background
    Interleukin-2 receptor subunit beta (IL2RB) is also known as CD122, which Belongs to the type I cytokine receptor family. Type 4 subfamily. IL2RB contains 1 fibronectin type-III domain. IL2RB / CD122 is involved in T cell-mediated immune responses, is present in 3 forms with respect to ability to bind interleukin 2. The low affinity form is a monomer of the alpha subunit and is not involved in signal transduction. The intermediate affinity form consists of an alpha/beta subunit heterodimer, while the high affinity form consists of an alpha/beta/gamma subunit heterotrimer. Both the intermediate and high affinity forms of the receptor are involved in receptor-mediated endocytosis and transduction of mitogenic signals from interleukin 2.
