Used in biomedical research to detect and quantify rat trypsin in biological samples such as serum, plasma, or tissue extracts. This ELISA kit is particularly useful in studies related to pancreatitis, pancreatic injury, or digestive enzyme regulation in rodent models. It enables researchers to assess trypsin levels with high sensitivity and specificity, supporting investigations in inflammation, enzyme secretion, and drug efficacy in preclinical studies. The assay is widely applied in pharmaceutical and academic laboratories for monitoring disease progression and evaluating therapeutic interventions.
