Active Interleukin 9 (IL9)
20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% SKL, 5% Trehalose and Proclin300.
Stability: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

Biological Activity Testing
(Interleukin 9, also known as IL-9, is a pleiotropic cytokine belonging to the group of interleukins. IL-9 secreted by CD4 helper cells that acts as a regulator of a variety of hematopoietic cells. This cytokine stimulates cell proliferation and prevents apoptosis. It functions through the interleukin-9 receptor (IL9R), which activates different signal transducer and activator (STAT) proteins namely STAT1, STAT3 and STAT5 and thus connects this cytokine to various biological processes. Besides, Interleukin 9 Receptor (IL9R) has been identified as an interactor of IL-9, thus a binding ELISA assay was conducted to detect the interaction of recombinant human IL-9 and recombinant human IL9R. Briefly, IL-9 were diluted serially in PBS, with 0.01% BSA (pH 7.4). Duplicate samples of 100uL were then transferred to IL9R-coated microtiter wells and incubated for 2h at 37. Wells were washed with PBST and incubated for 1h with anti-IL-9 pAb, then aspirated and washed 3 times. After incubation with HRP labelled secondary antibody, wells were aspirated and washed 3 times. With the addition of substrate solution, wells were incubated 15-25 minutes at 37. Finally, add 50uL stop solution to the wells and read at 450nm immediately. The binding activity of IL-9 and IL9R was shown in Figure 1, and this effect was in a dose dependent manner.Figure. The binding activity of IL-9 with IL9R)

NCBI and Uniprot Product Information
Accurate Molecular Mass: 18kDa
NCBI Description
The protein encoded by this gene is a cytokine that acts as a regulator of a variety of hematopoietic cells. This cytokine stimulates cell proliferation and prevents apoptosis. It functions through the interleukin 9 receptor (IL9R), which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. The gene encoding this cytokine has been identified as a candidate gene for asthma. Genetic studies on a mouse model of asthma demonstrated that this cytokine is a determining factor in the pathogenesis of bronchial hyperresponsiveness. [provided by RefSeq, Jul 2008]

Product Notes
The IL9 il9 (Catalog #AAA2122276) is an Active Protein and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is Gln19~Ile144. AAA Biotech's Interleukin 9 can be used in a range of immunoassay formats including, but not limited to, Cell Culture, Activity Assays. Researchers should empirically determine the suitability of the IL9 il9 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Interleukin 9, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
