Used in research settings to quantify levels of trypsin activating peptide in biological samples, aiding in the study of pancreatic function and inflammatory processes. Commonly applied in immunoassays to investigate conditions like pancreatitis, cystic fibrosis, and other disorders involving trypsinogen activation. Supports biomarker validation and drug development by providing a reliable method to monitor trypsin-related activity in cell cultures, serum, or urine samples.
