Preparation:
Produced from sera of rabbits immunized with highly pure Recombinant Human IL-9. Anti-Human IL-9-specific antibody was purified by affinity chromatography and then biotinylated.

Sandwich ELISA:
To detect Human IL-9 by sandwich ELISA (using 100 µL/well antibody solution), a concentration of 0.25–1.0 µg/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti-Human IL-9 (500-P29) as a capture antibody, allows the detection of at least 0.2–0.4 ng/well of Recombinant Human IL-9.

Western Blot:
To detect Human IL-9 by Western Blot analysis, this antibody can be used at a concentration of 0.1–0.2 µg/mL. When used with compatible secondary reagents, the detection limit for Recombinant Human IL-9 is 1.5–3.0 ng/lane, under either reducing or non-reducing conditions.

Package Information:
500-P29BT-1MG will be provided as 2 × 500 µg.

Target Information

Interleukin 9 (IL-9) is produced by activated T helper 2 (Th2) lymphocytes. IL-9 regulates cell types involved in classical Th2-associated asthma responses, including B and T lymphocytes, mast cells, eosinophils, and epithelial cells. The mouse IL-9 cDNA encodes a 144 amino acid precursor protein with an 18 amino acid signal peptide, forming a mature cysteine-rich protein (~14 kDa). Native mouse IL-9 is heavily glycosylated. TGF-β plays a role in differentiation of IL-17-producing T helper cells and inducible regulatory T cells by reprogramming Th2 cells to secrete IL-9, driving Th9 cell differentiation.
