  • Assay of free and complexed trypsinogen-2
    Patent number: 5976809
    Abstract: The invention relates to an immunoassay for trypsinogen-2 wherein an amount of analyte in a sample is measured, said analyte being either trypsin-2 complexed with alpha-1-antitrypsin (trypsin-2-AAT) in serum, or trypsinogen-2 in urine. According to a preferred embodiment, the trypsin-2-AAT complex or free trypsinogen-2 are measured by non-competitive methods employing at least two different antibodies. The methods are useful for the diagnosis of patients with pancreatic disease, especially pancreatitis.
