    The anti-interference ability of IL9 was excellent in Western blot, which avoided the interference problem in the experiment.

    04/14/2019

      This protein has high catalytic efficiency, high safety and high expression level, and is a precious resource in the field of scientific research.

      02/28/2019

        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 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.
