Definitions

  • Composition including [8] A kit for a method for detecting an RNA virus in a biological sample according to any one of [1] to [5].
  • the sample solution may be subjected to high temperature treatment in order to inactivate the proteolytic enzyme.
  • the high temperature treatment temperature include 91 ° C. to 99 ° C., preferably 93 ° C. to 97 ° C.
  • the high temperature treatment time include, for example, 1 second to 10 minutes, preferably 30 seconds to 5 minutes.
  • the sample liquid may be subjected to a high temperature treatment after the above heat insulating treatment, or may be subjected to only a high temperature treatment without the heat insulating treatment. Therefore, the method for preparing a sample solution for nucleic acid amplification of the present invention may further include a step of holding the mixed solution containing the biological sample and the additive for a certain period of time. In yet another aspect, the method for preparing a sample solution for nucleic acid amplification of the present invention may further include a step of retaining and / or heating the mixed solution containing the biological sample and the additive.
  • Thermal Cycler Dice registered trademark
  • Real Time System III PC
  • the PCR conditions were 52 ° C. for 5 minutes and 95 ° C. for 10 seconds, followed by a 45-cycle reaction with 95 ° C. for 5 seconds and 60 ° C. for 30 seconds as one cycle.
  • the amplification result was evaluated by comparing the Ct value with the control to which no additive was added. The results are shown in Table 2.
  • the biological sample suspension is diluted 10 to 20 times to 70 U / ml. It was confirmed that the Ct value was equivalent to that when high-concentration Proteinase K was added. Based on the above, even when RNA is detected from a sample in which an inactivated virus is spiked on a biological sample close to the actual sample, a combination of high-concentration Proteinase K, guanidin thiocyanate and / or sodium dodecyl sulfate is used as an additive of the present invention. Was confirmed to be promising.
  • the experiment was carried out as follows. That is, Proteinase K having a final concentration of 70 U / ml or 17.5 U / ml was added to the biological sample suspension, left at room temperature for 5 minutes, held at 55 ° C. for 5 minutes, and then heated at 95 ° C. for 5 minutes. After that, it was evaluated by the RT-qPCR method.
  • the RT-qPCR reagent used was the same as the reagent used in Example 1.
