Used for the quantitative detection of porcine lactase in research samples such as tissue homogenates, serum, or cell culture supernatants. This ELISA kit is specifically designed for use in immunological studies focusing on digestive enzyme expression in pig models. It enables researchers to measure lactase levels accurately, supporting studies on intestinal function, neonatal digestion, and gastrointestinal development in swine. Commonly applied in veterinary research, agricultural science, and preclinical studies related to lactose metabolism and gut health.
