  • Synonym
    IL7Ra,CD127
  • Source
    Human IL-7 R alpha, Mouse IgG2a Fc Tag(IL7-H5258) is expressed from human 293 cells (HEK293). It contains AA Glu 21 - Gly 236 (Accession # P16871-1 (I66T,V138I)).
    Predicted N-terminus: Glu 21
  • Molecular Characterization
    IL-7 R alpha Structure

    This protein carries a mouse IgG2a Fc tag at the C-terminus

    The protein has a calculated MW of 52.0 kDa. The protein migrates as 65-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >90% 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.

  • Background
    Interleukin-7 receptor subunit alpha (IL7Ra) is also known as CD antigen CD127, which belongs to the type I cytokine receptor family and type 4 subfamily. IL7Ra /CD127 contains 1 fibronectin type-III domain. IL7Ra /CD127 is expressed on various cell types, including naive and memory T cells and many others. IL7Ra /CD127 is receptor for interleukin-7 and also acts as a receptor for thymic stromal lymphopoietin (TSLP). The IL7 receptor is a heterodimer of IL7R and IL2RG. The TSLP receptor is a heterodimer of CRLF2 and IL7R.
