Abstract:
It is intended to provide a method of detecting the data of a target nucleic acid comprising bringing the target nucleic acid into contact with a probe having a sequence being complementary to at leas a part of the target nucleic acid sequence to form a hybrid of the target nucleic acid with the probe, and measuring a signal generated in an amount depending on the amount of the hybrid to thereby detect the data of the target nucleic acid, wherein the signal data are kinetically obtained. It is also intended to provide a method of detecting the data of a target nucleic acid comprising bringing the target nucleic acid into contact with a completely matching probe being completely complementary to at leas a part of the target nucleic acid sequence and one or more incompletely matching probes having a variation in at least a part of the completely matching probe to form hybrids of the target nucleic acid with the completely matching probe and with the incompletely matching probe, and detecting the data of the target nucleic acid based on the difference in the binding strength between the hybrids, characterized in that the signal data are kinetically obtained while continuously or stepwise altering the conditions of measuring or detecting the signals generated from the hybrids.

Abstract:
Provided are a method for exclusively selecting a duodenal fluid sample having a high possibility of containing pancreatic fluid and favorable sample suitability for subjecting to detection of a pancreatic disease marker by evaluating the quality of the sample prior to detecting the pancreatic disease marker, and a method for detecting a pancreatic disease marker using a duodenal fluid sample selected according to that method. Namely, a method is provided for selecting a duodenal fluid sample for detecting a pancreatic disease marker, comprising: (a1) a step of comparing the color depth of a duodenal fluid sample with a prescribed standard color, and (b1) a step of determining that a duodenal fluid sample is subjected to a test for a pancreatic disease marker if the color depth thereof is equal to or higher than the standard color, but that the duodenal fluid sample is not subjected to a test for a pancreatic disease marker if the color depth thereof is lower than the standard color.
Abstract:
It is intended to avoid any possibility of error attributed to a nucleic acid used as a standard, a probe or probe spot, etc. or enable correction thereof, to analyze the frequency of gene expression with high reproducibility and to analyze any change of primary structure in a sample nucleic acid. There is provided a method of analyzing the primary structure of at least one target base sequence present in a sample nucleic acid by detecting any signal from a sample nucleic acid hybrid composed of a probe and the sample nucleic acid, wherein any signal from a synthetic standard nucleic acid hybrid composed of the probe and a synthetic standard nucleic acid containing the at least one target base sequence is detected and on the basis of the signal from the synthetic standard nucleic acid hybrid, the signal from the sample nucleic acid hybrid is corrected to thereby effect analysis of the primary structure of the sample nucleic acid.

PROBLEM TO BE SOLVED: To recover only a lower layer among a plurality of layers subjected to layer separation with a simple configuration and operation.SOLUTION: The solution recovery auxiliary tool 1 is used when the lower layer is suctioned by a suction tube out of an upper layer and the lower layer subjected to layer separation in a container 2, and includes: a cylindrical barrel part 11 which has a through-hole 11a being open at both ends, can be inserted from one end side in the container 2, and can insert the suction tube in the through-hole 11a; a sealing member 12 which can be penetrated from a tip end of the suction tube by tightly sealing the opening at one end of the barrel part 11; and a shoulder part 13 which is provided by projecting outside on an outer peripheral surface of the barrel part 11, and is abutted with an upper surface of the container 2 when the barrel part 11 is inserted in the container 2.
Abstract:
PROBLEM TO BE SOLVED: To provide a feces treatment method and a feces treatment container capable of performing stable nucleic acid recovery. SOLUTION: In this feces treatment container 1 equipped with a feces sampling tool 100, a suspension holding part 110 and a treating liquid holding part 120, wherein a feces sample preparing solution S is stored in a solution holding container 121, a feces sample E collected by the feces sampling tool 100 is adjusted into a fixed amount by scraping off excessive feces by a guide part 112 when the feces sampling tool 100 is fitted to a feces holding part 110. Thereafter, by pressing the feces sample E by a piston 103, the feces sample E is shredded and dispersed into feces holding container 111 by a dispersion member 113. By pressing the feces holding container 111 into the solution holding container 121, a projection part 115 drills and breaks a sealing film 122, to thereby mix the dispersed feces sample E with the feces sample preparing solution S. The feces sample E is shredded and dispersed, to thereby enable stable nucleic acid recovery. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method for determining a target substance by which the ratio of the amounts of the target substance in samples can be determined more accurately by properly compensating the dispersion of measured results caused by the difference in initial qualities of samples, and the influence of analyzing operation or the like when determining the masses of the target substance in the two or more samples containing living body-associated substances of two or more kinds of living body species. SOLUTION: The method for determining the target substance in each of two or more samples containing a reference material different from the target substance and being a living body-associated substance of a living body species different from the target substance includes (a) a step for obtaining the ratio of the amounts of the reference material in each sample by measuring the amount of the reference material in each sample, (b) a step for measuring the amount of the target substance in each sample, and (c) a step for compensating the amount of the target substance in each sample obtained in the step (b) by using the ratio of the amounts of the reference material in each sample obtained in the step (a).
