Mouse IL-4 Protein, His Tag

  • Synonym
    IL4,BCGF1,BSF1
  • Source
    Mouse IL-4, His Tag (IL4-M52H5) is expressed from human 293 cells (HEK293). It contains AA His 21 - Ser 140 (Accession # P07750-1).
    Predicted N-terminus: His 21
  • Molecular Characterization
    Online(His 21 - Ser 140) P07750-1

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

    The protein has a calculated MW of 15.4 kDa. The protein migrates as 19-23 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 PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Background
    Interleukin-4, is a cytokine that induces differentiation of naive helper T cells (Th0 cells to Th2 cells). In the presence of IL-4 and IL-13, cytokines that are produced in a Th-2 type response, particularly during allergy and parasitic infections, macrophages become differentially activated, And this cytokine is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. Recently, researcher found that the cytokine IL-4 plays a key role in development of innate CD8+ T cells in the thymus of several gene-deficient mouse strains, including Itk, KLF2, CBP and Id3, without previous exposure to antigen.
