Used in biomedical research to quantify Porcine Pepsinogen 4 levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study gastric function and mucosal health in pig models, which is particularly valuable in veterinary research and agricultural studies. It supports investigations into digestive disorders, dietary effects on stomach physiology, and disease monitoring in swine. The assay is also useful in evaluating the impact of feed additives or pharmaceuticals on pepsinogen secretion. High sensitivity and specificity allow for accurate detection even in low-concentration samples, making it a reliable tool in experimental and diagnostic settings.
