Human IL-4 R alpha / CD124 Protein, Fc Tag

  • Synonym
    IL4R,CD124,IL4RA
  • Source
    Human IL-4 R alpha, Fc Tag (ILR-H5253) is expressed from human 293 cells (HEK293). It contains AA Met 26 - His 232 (Accession # P24394-1).
    Predicted N-terminus: Met 26
  • Molecular Characterization
    Online(Met 26 - His 232) P24394-1

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

    The protein has a calculated MW of 50.4 kDa. The protein migrates as 60-80 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.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Background
    IL-4 R alpha is also known as IL4R, CD124, IL-4RA.This gene encodes the alpha chain of the interleukin-4 receptor, a type I transmembrane protein that can bind interleukin 4 and interleukin 13 to regulate IgE antibody production in B cells. Allelic variations in this gene have been associated with atopy, a condition that can manifest itself as allergic rhinitis, sinusitis, asthma, or eczema. The binding of IL-4 or IL-13 to the IL-4 receptor on the surface of macrophages results in the alternative activation of those macrophages. Interleukin-4 receptor has been shown to interact with SHC1.
