Used in research settings to quantify diamine oxidase (DAO) levels in biological samples, this ELISA kit enables the study of histamine metabolism, particularly in relation to gut health and inflammatory responses. It supports investigations into conditions involving impaired DAO activity, such as histamine intolerance, food sensitivities, and certain gastrointestinal disorders. The kit is suitable for measuring DAO concentration in serum, plasma, or tissue homogenates, providing a reliable tool for immunological and metabolic research. Its high sensitivity and specificity make it valuable for preclinical studies and biomarker validation in mouse models.
