Cat. No. : IL9-216H
Description : Interleukin 9, also known as IL9, is a TH2 cytokine belonging to the group of interleukins. 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. IL-9 stimulates the proliferation of a variety of hematopoietic lineages through its interaction with a receptor of the cytokine receptor superfamily. IL-9 plays a role in the complex pathogenesis of bronchial hyperresponsiveness as a risk factor for asthma.
Source : Sf 21 Insect Cells.
Molecular Weight : The predicted molecular weight of Recombinant Human IL-9 is Mr 16-25 kDa. The protein resolves into multiple bands within this range on SDS-Page.
State Of Matter : Lyophilized.
Formulation : This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco's phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives present.
Purity : > 97% by SDS Page and analyzed by silver stain.
Endotoxin : < 0.1 ng per 1 µg as determined by the LAL method.
Biological Activity : The biological activity of Human IL-9 was determined by its ability to stimulate cell proliferation in the factor-dependent human megakaryocytic leukemic cell line, M07e. The expected ED50 for this effect is typically 0.5 - 1.0 ng/mL.
Storage And Stability : This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.

Q&As (6)

Ask a question
How is the clinical trial of IL9 progressing? 09/05/2022

Several 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.

How to obtain IL9? 03/13/2022

IL9 can be synthesized in the laboratory by biotechnological methods. Before clinical use, it needs to go through strict quality control and testing.

What is the action mechanism of IL9? 09/22/2021

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.

Howthe relationship between IL9 and other related cytokines? 05/02/2020

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.

What are the clinical applications of IL9? 09/26/2019

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.

What is the mechanism of action of IL9 in the treatment of asthma? 01/11/2019

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.
