Used in biomedical research to quantify porcine pepsinogen 1 levels in biological samples such as gastric fluids, serum, or tissue extracts. Enables monitoring of gastric mucosa health and function in pig models, supporting studies on digestive disorders, gastric acid secretion, and gastrointestinal disease progression. Commonly applied in veterinary research, preclinical studies, and food safety assessments where porcine gastric markers are relevant. The kit provides a reliable, high-throughput method for detecting early changes in pepsinogen levels associated with gastric damage or infection.
