Used for the quantitative measurement of pepsin activity in mouse biological samples such as gastric fluid, tissue homogenates, and serum. This ELISA kit enables researchers to assess pepsin levels as a marker for gastric function, reflux disease, or digestive disorders in mouse models. It is particularly useful in preclinical studies investigating gastrointestinal health, acid secretion, and the effects of drugs on proteolytic activity. The assay allows high-throughput analysis with high specificity and sensitivity, making it suitable for research in pharmacology, physiology, and gastroenterology.
