  • 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: 9796765
    Abstract: [Problem] The purpose of the present invention is to stably supply high-quality and highly uniform Wisteria floribunda agglutinin (WFA) that recognizes biologically important sugar-chain markers, to elucidate the sugar-chain recognition activity in detail, and to furthermore increase the specificity of the sugar-chain recognition activity. [Solution] The present invention involves the development of a technique for cloning genes for coding Wisteria floribunda agglutinin (WFA) and producing recombinant WFA having the same sugar-chain recognition activity as natural WFA from transformed bacteria. Natural WFA is reduced to thereby manufacture a reduced WFA monomer for specifically recognizing terminal GalNAc residue. A recombinant monomer WFA for recognizing LDN (GalNAc?1, 4GlcNAc) sugar chain, which is important as a diagnostic marker among sugar chains having a terminal GalNAc residue, is manufactured by introducing cysteine mutation to recombinant WFA or by C-terminal-side amino acid deletion.

  • Patent number: 7047195
    Abstract: A translation device which has both advantages of a table look-up translation device and advantages of a machine translation device by leading the user's utterance through a sentence template suitable for the user's intent of speech is realized. Since the translation device searches for sentence templates suitable for the user's intent of speech with an orally inputted keyword and displays retrieved sentences, the user's utterance can be lead. In addition, the user is free from a troublesome manipulation for replacing a word since an expression uttered by the user is inserted into a replaceable portion (slot) within the sentence template, and the translation device translates a resulting sentence with the replaced expression embedded in the slot.
