  • Patent number: RE46572
    Abstract: The present invention relates to a plasma biomarker for diagnosing hepatocellular carcinoma (HCC), in particular to the discovery of a protein in plasma using 2-D fluorescence differential gel electrophoresis (2-D DIGE), immunoprecipitation and Nano-liquid chromatography mass spectrometry (Nano-LC-MS/MS) system that was unknown on the basis of conventional techniques. By demonstrating the presence of liver carboxylesterase 1 (hCE1) in human plasma and confirming that its secretion level is higher in patients with HCC than in healthy volunteers, this invention may be used as a screening method to diagnose HCC at an early stage.
