Used for the quantitative measurement of pepsin activity in rabbit biological samples such as gastric secretions, tissue homogenates, or cell culture supernatants. This ELISA kit enables researchers to assess pepsin levels as a marker of gastric function or digestive health in experimental models. It is particularly useful in studies related to gastrointestinal diseases, enzyme regulation, and the effects of pharmaceuticals on proteolytic activity. The assay provides high specificity and sensitivity, allowing accurate detection of active pepsin without interference from pepsinogen or other proteases. Commonly applied in preclinical research and veterinary diagnostics.
