Background:
Interleukin 9 (IL-9) is a cytokine secreted by TH2 lymphocytes that acts as a regulator of a variety of hematopoietic cells, stimulates cell proliferation and prevents apoptosis (1,2). It functions through the interleukin 9 receptor (IL9R), which activates different signal transducer and activator (STAT) proteins (3). The IL-9 gene has been identified as a candidate gene for asthma (4). Genetic studies on a mouse model of asthma demonstrated that this cytokine is a determining factor in the pathogenesis of bronchial hyperresponsiveness (5).

Buffer:
IL-9 Antibody is supplied in PBS containing 0.02% sodium azide.
Concentration:
1 mg/mL
Conjugate:
Unconjugated
DISCLAIMER:
Optimal dilutions/concentrations should be determined by the end user. The information provided is a guideline for product use. This product is for research use only.
Immunogen:
Anti-IL-9 antibody (7495) was raised against a peptide corresponding to 16 amino acids near the carboxy terminus of human IL-9.

The immunogen is located within the last 50 amino acids of IL-9.
ISOFORMS:
Human IL-9 has one isoform (144aa, 16kD). Mouse IL-9 has one isoform (144aa, 16kD) and Rat IL-9 also has one isoform (144aa, 16kD). 7495 can detect human isoform, but cannot detect mouse and rat.
