Used in research settings to measure zonulin levels in mouse samples, this ELISA kit helps investigate intestinal permeability and gut barrier function. It is commonly applied in studies related to inflammatory bowel disease, irritable bowel syndrome, food sensitivities, and autoimmune conditions such as type 1 diabetes. Researchers use it to assess how various treatments, diets, or drugs affect tight junction integrity in the gut. The kit enables quantification of zonulin, a biomarker associated with increased gut permeability, supporting studies on the gut-immune axis and the role of the microbiome in health and disease.
