  • 線性度：

    To assess the linearity of the assay, samples were spiked with high concentrations of human Trypsin-2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

    8. results suggest that trypsinogen-2 is a more sensitive marker than amylase, and it can be useful in early diagnosis of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. PMID: 21792081
    9. A genetic variant of PRSS2 may contribute to the low prevalence of pancreatitis in primary hyperparathyroidism patients. PMID: 20625975

    13. Results do not support the urinary trypsinogen-2 dipstick test (UTDT) to replace standard plasma amylase for the diagnosis of AP, however, the test demonstrated an adequate sensitivity to be used for rapid early screening of AP in daily clinics. PMID: 19752771
    14. Results indicate that up-regulation of anionic trypsinogen in pancreatic diseases does not affect physiological trypsinogen activation, but significantly limits trypsin generation under potential pathological conditions. PMID: 12709065
    15. High levels of pulmonary trypsin-2 may be associated with the development of bronchopulmonary dysplasia in preterm infants. PMID: 12949286

    18. Co-localization of trypsin-2 and MMP-9 resulted in intracellular proMMP-9 processing that represented fully or partially activated MMP-9. PMID: 18062964
    19. A loss of function polymorphism (G191R) of anionic trypsinogen (PRSS2) confers protection against chronic pancreatitis. PMID: 18362849
    20. A fusion with PRSS1 is associated with hereditary pancreatitis. PMID: 18461367
