Human IL-9 Protein, premium grade

  • Synonym
    Interleukin-9,IL-9,Cytokine P40
  • Source
    Human IL-9 Protein, premium grade(IL9-H5214) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Ile 144 (Accession # P15248-1).
    Predicted N-terminus: Gln 19
    Human IL-9 Protein, premium grade (IL9-H5214), designed for preclinical stage, has the same activity and performance with GMP Human IL-9 Protein, which enables a seamless transition from preclinical development to clinical phases. Premium Grade product offer a cost efficient alternative of GMP Grade products for the early development phase when safety of raw materials is not top priority. By using Premium Grade products in early development phase, you can transition easily into clinical and commercial phase without need to revalidate the raw materials and modify manufacturing process.
  • Molecular Characterization
    IL-9 Structure

    This protein carries no "tag".

    The protein has a calculated MW of 14.1 kDa. The protein migrates as 30 kDa±3 kDa under reducing (R) condition, and 30 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.01 EU per μg by the LAL method.
  • Host Cell Protein
    <0.5 ng/µg of protein tested by ELISA.
  • Host Cell DNA
    <0.02 ng/μg of protein tested by qPCR.
  • Sterility
    Negative
  • Mycoplasma
    Negative.
  • Purity

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

SDS-PAGE
IL-9 SDS-PAGE

Human IL-9 Protein, premium grade on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

SEC-MALS
IL-9 MALS images

The purity of Human IL-9 Protein, premium grade (Cat. No. IL9-H5214) is more than 95% and the molecular weight of this protein is around 18-25 kDa verified by SEC-MALS.

Bioactivity-ELISA
 IL-9 ELISA

Immobilized Human IL-9 Protein, premium grade (Cat. No. IL9-H5214) at 5 μg/mL (100 μL/well) can bind Human IL-9R, Fc Tag (Cat. No. ILR-H5251) with a linear range of 2-78 ng/mL (QC tested).

  • 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.
