  • Composition for Analyzing Nucleic Acid
    Publication number: 20120295252
    Abstract: A composition for analyzing nucleic acid that contains luciferase for which reactivity to dATP is equal to or less than 1/400 reactivity to ATP. A method for analyzing nucleic acid that comprises the use of the composition. A kit for analyzing nucleic acid comprising the composition. The method provides for an inexpensive, highly accurate and highly sensitive nucleic acid analysis that uses dATP instead of an expensive reagent having a low reactivity to DNA polymerase.
    Type: Application

  • Light emitting method of acridinium derivative and method of detecting substance to be examined using same
    Patent number: 5879888
    Abstract: A light emitting method of an acridinium ester, comprising reacting said acridinium ester and a superoxide anion, and a method of detecting a substance to be examined, comprising detecting a light emitted by reacting a superoxide anion with an acridinium ester used as a label are described. It is possible to carry out the reaction not under strongly alkaline conditions but around the neutral point and to generate strong luminescence which is stable over a long period of time.
