Detection of Human IL‑9 by Western Blot. Western blot shows lysates of human Th2 cells treated with (1) anti-CD3 and anti-CD28, (2) anti-CD3, anti-CD28, Recombinant Human IL‑2 (Catalog # 202-IL), Recombinant Human IL‑4 (Catalog # 204-IL), and Mouse Anti-Human IFN‑ gamma Monoclonal Antibody (Catalog # MAB285) or (3) anti-CD3, anti-CD28, Recombinant Human IL‑2 (Catalog # 202-IL), Recombinant Human IL‑4 (Catalog # 204-IL), Mouse Anti-Human IFN‑ gamma Monoclonal Antibody (Catalog # MAB285), and Recombinant Human TGF‑ beta 1 (Catalog # 240-B). PVDF membrane was probed with a 1:1000 dilution of Rabbit Anti-Human IL‑9 Monoclonal Antibody (Catalog # MAB2091) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for IL‑9 at approximately 35-40 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Interleukin-9 (IL-9) is a heavily glycosylated cytokine with a 14 kDa peptide backbone 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.
