Mouse IL-9 Recombinant Protein
ELISA Detection (Routinely Tested)
0.5 mg/ml
Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Recommended Assay Procedures

ELISA Detection: Biotinylated D9302C12 antibody (Cat. No. 554473) is useful as a detection antibody for a sandwich ELISA for measuring mouse IL-9 protein levels.  Biotinylated D9302C12 antibody can be paired with the D8402E8 antibody (Cat. No. 551218) as the capture antibody, and with recombinant mouse IL-9 as the standard. Biotinylated D9302C12 antibody should be titrated (0.5 - 2.0 µg/ml) to determine optimal concentration for ELISA detection. An appropriate range of concentrations of the mouse IL-9 standard for obtaining a linear standard curve is 4 ng/ml to 30 pg/ml. For maximal sensitivity, BD Biosciences recommends an overnight incubation (4°C) of samples/standards with the coated capture antibody. For specific methodology, please visit our website,, and go to the protocols section or the chapter on ELISA in the Immune Function Handbook.

This ELISA pair shows no cross-reactivity with any of the cytokines tested (e.g., mouse IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-10, IL-12 p70, IL-15, GM-CSF, IFN-γ, MCP-1, TCA-3, TNF; human IL-1α, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12 p70, IL-12 p40, IL-13, IL-15, G-CSF, GM-CSF, IFN-γ, lymphotactin, MCP-1, MCP-2, MIP-1α, MIP-1β, NT-3, PDGF-AA, sCD23 , SCF, TNF, LT-α, VEGF; rat IL-2, IL-4, IL-6, IL-10, GM-CSF, IFN-γ, TNF).

Neutralization: The NA/LE format of this clone (Cat. No. 554472) is recommended for functional assays.

Product Notices

  1. Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at
  2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  3. Please refer to for technical protocols.
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The D9302C12 monoclonal antibody specifically binds to the multifunctional mouse cytokine, Interleukin-9 (IL-9). IL-9 is a 126 amino acid-long glycoprotein that is produced by various subsets of activated CD4+ T cells. IL-9 acts on target cells by binding to and signaling through the heterodimeric IL-9 receptor (IL-9R) complex that is comprised of transmembrane IL-9 receptor alpha (IL-9Rα) and common gamma chain (γc) subunits. IL-9 can promote the survival, growth, proliferation and/or differentiation of various cell types including thymocytes, T cells, B cells, mast cells, and hematopoietic progenitor cells. IL-9 can augment IL-4-induced IgE and IgG1 production from lipopolysaccharide-primed mouse B cells and induce granzyme and high-affinity IgE receptor gene expression by mouse T helper cell clones and mast cell lines. IL-9 plays an important role in vivo in helminth elimination. The D9302C12 antibody neutralizes mouse IL-9 bioactivity.

Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
