Used for quantifying pepsin enzyme activity in rat samples, this ELISA kit is widely applied in gastrointestinal research. It helps assess gastric function and monitor pepsin levels in studies related to acid reflux, gastritis, and digestive disorders. The kit enables high-throughput analysis in preclinical studies, supporting drug development for gastric diseases. It is also useful in evaluating the effects of treatments on pepsin secretion and enzyme activity in laboratory settings.
