Used to quantitatively measure human interleukin-37 (IL-37), a cytokine involved in suppressing inflammatory responses, in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is widely applied in immunological research to study the role of IL-37 in chronic inflammatory diseases, autoimmune disorders, and cancer. It enables researchers to monitor IL-37 levels in clinical samples, aiding in the evaluation of disease progression and response to anti-inflammatory therapies. Due to IL-37's role as a natural brake on innate immunity, this kit supports studies focused on immune regulation and the development of novel therapeutics targeting inflammatory pathways.
