Anti-IL9 Antibody

A rabbit polyclonal antibody targeting interleukin-9 (IL9), supplied by Antibodies.com as a 100 µl aliquot at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol. This unconjugated primary antibody is validated for western blot and shows reactivity with human, mouse, and rat samples, making it useful for cross-species comparative studies of cytokine signaling.

IL9 is a Th2-associated cytokine involved in mast cell activation, allergic inflammation, and immune regulation. Western blot detection of endogenous IL9 protein is the principal application, supporting characterization of cytokine expression in activated T cell cultures, profiling of immune responses in asthma or helminth infection models, and investigation of IL9 signaling in lymphoma research.

The 50% glycerol buffer composition permits storage at -20 °C without freezing, preserving antibody activity across repeated freeze-thaw cycles when the reagent is aliquoted. Sodium azide serves as a microbial preservative to maintain reagent stability over the working shelf life.

Host species is rabbit, clonality is polyclonal, and the conjugate is unconjugated, so the reagent pairs with standard secondary detection reagents including HRP- or fluorophore-conjugated anti-rabbit IgG. For research use only.
