Used in biomedical research to measure gastrin-17 hormone levels in human serum or plasma samples. Helps assess gastric acid regulation and diagnose gastrointestinal disorders such as atrophic gastritis, gastric ulcers, and Zollinger-Ellison syndrome. Supports studies on stomach function, hormonal imbalances, and the impact of *Helicobacter pylori* infection. Commonly used in clinical labs and research settings for accurate, high-throughput quantification of gastrin-17.
