  • Synonym
    Interleukin-9,IL-9,Cytokine P40
  • Source
    Human IL-9 Protein, His Tag(IL9-H52H9) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Ile 144 (Accession # P15248-1).
    Predicted N-terminus: Gln 19
  • Molecular Characterization
    IL-9 Structure

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

    The protein has a calculated MW of 16.0 kDa. The protein migrates as 33-37 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Background
    Interleukin-9 (IL-9) is expressed primarily by activated T cells. The growth factor and anti apoptotic activities of IL-9 on multiple transformed cells suggest a potential role for the cytokine in tumourigenesis. IL-9 has also been proposed as a candidate gene for asthma IL-9 is a Th2-derived cyto kine that has been reported to regulate T and B cell function. IL-9was first isolated as a factor capable of sustaining the long-termgrowth of murine T cell clones, but has since been demon strated to have in vitro activities on mast cells, erythroid pro genitors, and B cell Ig expression.
