  • Plant-derived proteoglycan and application thereof
    Patent number: 12318472
    Abstract: The present invention relates to a plant proteoglycan obtained from gum arabic obtained from a trunk or branch of Acacia plant (Acacia Senegal Willdenow or Acacia Seyal Delile), having a weight average molecular weight of 900,000-3,500,000, and having a total aldehyde content of not more than 2.0 ?mol equivalent/g. A plant proteoglycan having physiological activity equal to or higher than that of animal proteoglycan can be provided by the present invention.
    Type: Grant
    Filed: September 24, 2019
    Date of Patent: June 3, 2025
    Assignee: NOF CORPORATION
    Inventors: Masao Hara, Mamoru Tsuchida

  • Nonspecific hybridization inhibitors, clinical examination reagents and clinical examination method
    Patent number: 8252531
    Abstract: The present invention relates to an inhibitor capable of increasing accuracy of the reaction in hybridization, and inhibiting nonspecific hybridization, a clinical diagnostic reagent, and a method of clinical analysis whereby nonspecific hybridization in clinical analysis is inhibited, and a target nucleic substance is detected easily with high accuracy. The inhibitor and the clinical diagnostic reagent contains polymer (H) having a nonspecific hybridization inhibitory action. The polymer has in its molecule at least one of carboxyl and sulfone groups, and phosphorylcholine-like groups, and has a weight average molecular weight of 1000 to 5000000. The method of clinical analysis includes contacting a sample with a test agent capable of hybridizing with a specific nucleic substance in the presence of the inhibitor.
