  • Kit for tracking and diagnosing degree of progressive chronic hepatitis and liver fibrosis by measuring asialo (alpha)1-acid glycoprotein as hepatocellular injury marker and use thereof
    Patent number: 11493521
    Abstract: Exemplary embodiments of the present invention relate to rapidly and easily test initial liver disease and more particularly to a monoclonal antibody for ?1-acid glycoprotein, a diagnosis kit for tracking progressive chronic hepatitis and liver fibrosis in an initial phase of liver disease by measuring the concentration of asialo-?1-acid glycoprotein (AsAGP) as a hepatocyte injury marker in a sample using the antibody, and a use thereof. Further, embodiments of the present invention provide a kit for specifically determining the degree of progressive chronic hepatitis and hepatic fibrosis from a blood sample and an immunochromatography strip, comprising a HRP-RCA II (Ricinus communis agglutinin II) conjugate or a Gold-RCA II conjugate specifically binding to asialo ?-1 acid glycoprotein.
