Description : | Interleukin-9 (IL-9) is encoded by the IL9 gene and produced by T-cells and specifically by CD4+ helper cells. IL-9 was originally identified as a cytokine found in the conditioned medium of a human T cell leukemia virus type I (HTLVI) transformed T cell line. It functions through the IL-9 receptor, which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. IL-9 can support the growth of IL-2 independent and IL-4 independent helper T-cells. Human IL-9 has approximately 56 % amino acid sequence identity with murine IL-9. 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 hyper-responsiveness. |

Purity : | > 95 % by SDS-PAGE and HPLC analyses. |
Storage : | This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 centigrade to -70 centigrade. Avoid repeated freeze/thaw cycles. |
Reconstitution : | Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 centigrade. Further dilutions should be made in appropriate buffered solutions. |
Quality Statement : | Our GMP proteins are produced according to relevant sections of the following documents: WHO TRS, No. 822, 1992 Annex 1, Good Manufacturing Practices for Biological Products; USP Chapter 1043, Ancillary Materials for Cell, Gene and Tissue-Engineered Products and USP Chapter 92, Growth Factors and Cytokines Used in Cell Therapy Manufacturing. |

Write a reviewThe anti-interference ability of IL9 was excellent in Western blot, which avoided the interference problem in the experiment.
This protein has high catalytic efficiency, high safety and high expression level, and is a precious resource in the field of scientific research.
The reproducibility of IL9 is very good, which can reduce the error in the experiment and improve the repeatability of the experiment.
Q&As (6)
Ask a questionSeveral clinical trials are currently underway to evaluate the safety and effectiveness of IL9 in treating conditions such as asthma and allergies. However, the research is still in its early stages and more data are needed.
IL9 can be synthesized in the laboratory by biotechnological methods. Before clinical use, it needs to go through strict quality control and testing.
By binding to specific receptors, IL9 can activate relevant signaling pathways and regulate the development and function of immune cells. It can affect the activity of a variety of immune cells, such as T cells and macrophages.
IL9 has cross-action with other cytokines, which can regulate the expression and function of each other. For example, IL9 can promote the production of IL4 and IL13, and IL4 and IL13 can also promote the secretion of IL9.
IL9 can be used to treat certain inflammatory diseases, such as asthma and skin allergies. It can regulate the response of the immune system and reduce the symptoms of related diseases.
The mechanism of action of IL9 in asthma treatment is not fully understood, but studies have shown that it can reduce the infiltration of inflammatory cells and the release of inflammatory mediators, thereby reducing the symptoms of asthma.
