  • AGENT THAT MODULATES PHYSIOLOGICAL CONDITION OF PESTS, INVOLVED IN INSECT VESICLE-FUSING ATPASE ACTIVITY
    Publication number: 20110207775
    Abstract: The present invention provides an agent that modulates physiological condition of pests, wherein the agent has an ability to modulate the activity of an insect vesicle-fusing ATPase; a method for assaying pesticidal activity of a test substance, which comprises measuring the activity of a vesicle-fusing ATPase in a reaction system in which the vesicle-fusing ATPase contacts with a test substance, and the like.

  • Irreversible immobilization of enzymes into polyurethane coatings
    Publication number: 20080108745
    Abstract: A method of irreversibly immobilizing an enzyme in a polyurethane and an enzyme-containing polyurethane having a degree of immobilization of the enzyme of approximately 100%. The synthesis of waterborne polyurethanes in the presence of enzyme has enabled the irreversible attachment of the enzyme to the polymeric matrix. The distribution of immobilized enzyme as well as activity retention are homogeneous within the polyurethane. Decreasing ECC hydrophobicity, via the use of a less hydrophobic polyisocyanate prepolymer during polymerization, significantly enhanced the intrinsic activity of the ECC.
