  • Patent number: 11571473
    Abstract: An examination system that recognizes a glycosylated antigen in Dane particles of hepatitis B virus (HBV) and a neutralizing antibody that recognizes the glycosylated antigen and that exhibits an infection-inhibiting activity. It was elucidated that Dane particles are associated with specific glycan structures, and this enabled the construction of a new detection system for infectious, i.e., nucleic acid-containing, hepatitis B virus particles and the provision of a neutralizing antibody that recognizes a glycosylated antigen and that exhibits an infection-inhibiting activity.

  • Patent number: 9796761
    Abstract: The present invention is directed to developing a glycan markers capable of detecting a hepatic disease, and more specifically to developing a glycan marker indicating a hepatic disease-state. Furthermore, the present invention is also directed to developing a glycan marker capable of distinguishing hepatic disease-states with the progress of hepatocarcinoma. The present inventors identified, among the serum glycoproteins, glycopeptides and glycoproteins in which a glycan structure specifically changes due to a hepatic diseases including hepatocarcinoma and provide these as novel glycan markers (glycopeptide and glycoprotein) specific to hepatic disease-states.
