    摘要: High impact resistant thermoplastic resins are produced in three steps: (a) graft polymerizing a minor amount of unsaturated monomer onto a major amount of diene type rubber polymer in latex form, (b) mixing the grafted diene type rubber latex with a monomer or monomers, extracting the grafted rubber polymer particles into the monomer phase and separating and discarding the water phase to obtain a grafted rubber polymer particle dispersed monomer solution, and (c) bulk polymerizing the resulting rubber polymer particle dispersed monomer solution.

    摘要: The present invention provides an inexpensive DNA sequencing method with high-sensitivity. The method of the present invention comprising the steps of, adding an given amount of dATP for step by step complementary strand synthesis and subtracting the background luminescence intensity caused by dATP from the measured luminescence intensity to obtain the luminescence intensity involved in complementary strand synthesis.

    摘要: Accurate and sensitive sequencing in pyrosequencing is achieved by allowing complementary strand synthesis reaction to proceed homogeneously and completely in a short time while performing luminescence reaction for a sufficiently long time. DNA as a sequencing target is immobilized on the surface of a solid support. Nucleic acid substrates are injected from a dispenser to the support site where complementary strand synthesis is in turn performed rapidly and completely in a short time under a small reaction volume. Next, the support together with the product thereon is moved into a luminescence reaction solution where luminescence reaction is in turn performed. Thus, a DNA complementary strand synthesis reaction site and a luminescence reaction site are completely separated. The support surface is also washed by dipping the support in the luminescence reaction solution that contains a luminescence reagent and an enzyme that degrades redundant nucleic acid substrates.
