Flow cytometric analysis of IL-9 expressed in stimulated human lymphocytes. PBMC were cultured (5 d) with plate-bound NA/LE Mouse Anti-Human CD3 (Cat. No. 555329; 10 μg/ml, coated overnight at 4°C) and soluble NA/LE Mouse Anti-Human CD28 (Cat. No. 555725; 1 μg/ml) antibodies plus recombinant Human IL-2 (Cat. No. 554603; 10 ng/ml), IL-4 (Cat. No. 554605; 50 ng/ml), and TGF-β (Corning; Cat. No. 354039; 10 ng/ml) proteins and NA/LE Mouse Anti-Human IFN-γ antibody (Cat. No. 554698; 10 μg/ml). The cells were restimulated (5 h) with PMA (Sigma P8139; 50 ng/ml) and ionomycin (Sigma I9657; 1 μg/ml) in the presence of BD GolgiStop™ Protein Transport Inhibitor (Cat. No. 554724). The cells were washed, and then fixed and permeabilized using the BD Cytofix/Cytoperm™ Fixation/Permeablization Kit (Cat. No. 554714) and stained with BD Horizon™ BV421 Mouse Anti-Human IL-9 antibody (Cat. No. 564254). A two-parameter flow cytometric contour plot showing the coexpressed levels of IL-9 versus Autofluorescence were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometric analysis was performed using a BD LSRII™ System.

- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.

The MH9A3 monoclonal antibody specifically binds to human interleukin-9 (IL-9). Human IL-9 is a multifunctional cytokine and a member of the type I cytokine (hematopoietin) family that includes IL-2, IL-4, IL-7, IL-15 and IL-21. This cytokine is encoded by the IL9 gene that is resident on chromosome 5q31.1. IL-9 is expressed by activated CD4-positive T helper cells, by some transformed T cells and by eosinophils, mast cells and neutrophils. IL-9 induces the proliferation, differentiation, and effector function of various cell types including T lymphocytes, B lymphocytes, mast cells, eosinophils, neutrophils, hematopoietic cells and epithelial cells. It potentiates the interleukin-4-induced IgM, IgG and IgE responses by human B lymphocytes. IL-9 has been implicated in human allergic disorders such as asthma and malignancies such as Hodgkin's disease. IL-9 exerts its biological activities through binding to the surface IL-9 receptor (IL-9R) complex comprised of the IL-9R alpha subunit (IL-9Rα; CD129) and the common cytokine receptor gamma subunit (γc; CD132). IL-9 signaling through its receptor includes activation of the Janus kinases 1 and 3 ( JAK1 and JAK3) and activation of Signal transducer and activator of transcription 1, 3 and 5 factors (STAT1, STAT3 and STAT5).
The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.
