Used in research settings to quantify levels of Pepsinogen C in biological samples, particularly rat serum or tissue extracts. Helps in studying gastric function and monitoring changes in the gastric mucosa. Commonly applied in preclinical studies related to gastrointestinal diseases, such as gastritis, gastric atrophy, and ulcer development. Supports investigation into the effects of drugs, pathogens, or dietary factors on stomach physiology. The kit enables high-throughput, sensitive, and specific detection, making it valuable for biomarker validation and translational research.
