Detection of IL‑9 in Human PBMC by Flow Cytometry.
Human PBMC untreated (top panel) or treated with 50 ng/mL PMA and 500 ng/mL calcium ionomycin for 24 hours (bottom panel) were stained with Mouse Anti-Human IL‑9 Monoclonal Antibody (Catalog # MAB209) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B) and Human IFN‑ gamma Fluorescein-conjugated Monoclonal Antibody (Catalog # IC285F). Quadrant markers were set based on control antibody staining (Catalog # MAB0041). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Interleukin-9 (IL-9) is a 14 kDa glycosylated cytokine that is secreted by CD4+ Th2 cells. It supports the growth of multiple hematopoietic cell types including Th cells, germinal center B cells, macrophages, mast cells, neutrophils, megakaryocytes, and erythrocytes. IL-9 exerts its biological effects through a receptor complex composed of IL-9 R and the common gamma chain. Mature human IL-9 shares 57% amino acid sequence identity with mouse and rat IL-9.
