MH9A3_BV421_IL-9_Antibody_1_040624
Th2-polarized human lymphocytes were stimulated with Cell Activation Cocktail (with Brefeldin A) (Cat. No. 423303) for 6 hours and then surface stained with anti-human CD3 (clone UCHT1) APC. Cells were then fixed, permeabilized, and intracellularly stained with anti-human IL-9 (clone MH9A3) Brilliant Violet 421™ (left), or mouse IgG1, κ Brilliant Violet 421™ isotype control (right).

Description

IL-9 is a potent, T cell-derived, T cell growth factor which can also enhance mast cell activity and IL-3- or IL-4- dependent proliferation of bone marrow-derived mast cells. IL-9 synergizes with erythropoietin to promote erythroid colony formation. IL-9 has also been reported to protect human T cells from apoptosis induced by IL-2 withdrawal. IL-9 is upregulated in human eosinophils by TNF-α and IL1-β. IL-9 has been reported to downregulate the oxidative burst in activated human alveolar macrophages and induce TGF-β production. The MH9A3 antibody reacts with human IL-9. The MH9A3 antibody can inhibit IL-9 bioactivity in vitro.

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Brilliant Violet 421™ excites at 405 nm and emits at 421 nm. The standard bandpass filter 450/50 nm is recommended for detection. Brilliant Violet 421™ is a trademark of Sirigen Group Ltd.
