Used in research settings to quantify levels of interleukin-37B in biological samples such as serum, plasma, or cell culture supernatants. Enables scientists to study the role of IL-37B in inflammatory diseases, autoimmune conditions, and immune regulation. Commonly applied in studies related to chronic inflammation, sepsis, rheumatoid arthritis, and cancer to understand cytokine dynamics and evaluate therapeutic interventions. Provides a sensitive and specific method for detecting low concentrations of IL-37B, supporting biomarker discovery and validation in clinical and preclinical research.
