Used for the quantitative detection of lactase enzyme activity in porcine (pig) samples, this ELISA kit is essential in research and diagnostic laboratories studying digestive function and enzyme deficiencies in swine. It enables accurate measurement of lactase levels in tissue extracts or biological fluids, supporting studies on lactose digestion, intestinal health, and nutritional metabolism in pigs. The assay is also valuable in evaluating the effectiveness of dietary interventions or genetic factors affecting lactase expression. Due to its specificity and sensitivity, the kit is widely used in veterinary research, agricultural science, and animal health monitoring.
