Used to measure levels of interleukin-17E (IL-17E), also known as IL-25, in human biological samples such as serum, plasma, or cell culture supernatants. This kit is widely applied in immunology research to study type 2 immune responses, as IL-17E plays a key role in promoting allergic inflammation, asthma, and defense against parasitic infections. It is also used in clinical and research settings to investigate autoimmune diseases, inflammatory conditions, and the role of IL-17E in regulating T helper cell activity. The assay enables sensitive and specific quantification, supporting both basic research and biomarker validation studies.
