  • Synonym
    IL5Ra,CD125
  • Source
    Biotinylated Human IL-5 R alpha Protein, Avitag,Fc Tag(ILA-H82F5) is expressed from human 293 cells (HEK293). It contains AA Asp 21 - Trp 342 (Accession # Q01344-1).
    Predicted N-terminus: Gly
  • Molecular Characterization
    IL-5 R alpha Structure

    This protein carries an Avi tag (Avitag™) at the N-terminus, followed by a human IgG1 Fc tag.

    The protein has a calculated MW of 64.9 kDa. The protein migrates as 70-90 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • 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 PBS, pH7.4 with trehalose as protectant.

    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.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE

  • Background
    Interleukin-5 receptor subunit alpha (IL5RA) is also known as IL-5 receptor subunit alpha, IL-5R subunit alpha and CD125,which is a single-pass type I membrane protein that belongs to the type I cytokine receptor family and type 5 subfamily.IL5R, a heterodimer of an alpha and a beta subunit, is expressed on eosinophils and basophils. IL5RA / CD125 is the receptor for interleukin-5 (IL5) and the alpha chain can bind to IL5. The WSXWS motif of IL5RA appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.The beta subunit of IL5R is common to the IL3, IL5 and GM-CSF receptors.
