    摘要: PROBLEM TO BE SOLVED: To provide a method for detecting a malaria parasite in which malaria-infected red blood cell can simply and rapidly be detected and falciparum malaria can be discriminated from other malaria and infection rate can be determined and to provide a reagent for detection used for the method and to provide a reagent for partial lysis of cell membrane of red blood cell. SOLUTION: The reagent for partial lysis of a cell membrane of a red blood cell infected with a malaria parasite comprises a first surfactant which has predetermined lysing ability with respect to the red blood cell membrane and a second surfactant which has weaker lysing ability than that of the first surfactant; wherein the reagent has a pH of 5 to 7 and an osmotic pressure of 200 to 300 mOsm/(kg H 2 O); and wherein the reagent partially lyses the cell membrane of the malaria infected red blood such that a malaria parasite is retained in the red blood cell and fluorescent dye transmits the cell membrane. The malaria infected red blood cell is detected from scattered light information and fluorescent information obtained by introducing a sample in which the detection reagent is mixed with a whole blood specimen into a flow cytometer.

    摘要: PROBLEM TO BE SOLVED: To provide a method for detecting mutation (G681A mutation) at the 681 position of the cDNA of a CYP2C19 gene. SOLUTION: The method for detecting the mutation comprises carrying out a melting curve analysis by amplifying a region containing a G681A mutation by a PCR, using a nucleic acid probe having a terminus labeled with a fluorochrome, regulated so that the fluorescence may be reduced when hybridized, having a base sequence complementary to a base sequence started from the base number 189 in a specific base sequence and having 20-35 base length, and further having the 3'-terminus labeled with the fluorochrome, and measuring the fluorescence of the fluorochrome, and detecting the mutation based on the result of the melting curve analysis.
