    摘要: A method for examining nucleotide sequences of a sample includes adding a group of primers of multiple species to a solution containing the sample and simultaneously synthesizing complementary strands at each of the multiple regions containing the nucleotide sequences; designing the DNA probes with specific sequences elongate the complementary strands by the presence or absence of mutations in the nucleotide sequences, wherein the same number of such DNA probes and the nucleotide sequences are used for complementary strand synthesis; using the nucleotide sequences or their complementary sequences as a template to convert pyrophosphate produced during the elongation reaction to ATP which then reacts with chemiluminescent substrates to develop luminescence to be detected. According to the method, sensitivity is greatly increased by amplification of the amount of pyrophosphate produced in synthesis of the complementary strands without amplifying the copies of nucleotide sequences.

    摘要: A single molecule of single-stranded sample DNA (7) having a bead (5) at one end and a magnetic bead (6) at the other end is extended and fixed in the field of view of a fluorescent microscope by using a magnetic force (11) and a laser trap (3), and a primer (8) is bonded thereto, followed by elongation reaction (10) using polymerase. Only a single chemically modified nucleotide (9) labeled with at least one fluorophore which varies depending on the kind of the base is incorporated. Only the single fluorophore incorporated is measured as a fluorescence-microscopic image by evanescent irradiation (13) with exciting laser beams, and the kind of the base is determined from the kind of the fluorophore. The fluorophore labeling the nucleotide incorporated is released by evanescent irradiation (13) with ultraviolet laser beams (2), and the next nucleotide is incorporated. DNA sequencing is carried out by repeating the above procedure. The base sequence determination can be carried out by using the single DNA molecule, so that a DNA base sequence of hundreds kilos or more bases can be efficiently determined.

A plurality of capillaries or grooves packed with various kinds, respectively, of probe particles are arrayed in parallel, and one of particles contained in each capillary or groove is injected into another capillary or groove to produce a probe array in which the various kinds of probe particles are arrayed in a constant and definite order. Various fluorophore-labeled DNA's are measured at the same time by attaching various probes to particles, respectively, of different sizes.

    摘要: DNA molecule length can be measured with high precision and efficiency by 1) using such means as electrophoresis gel migration to orient a DNA molecule having a fluorescence label at both its termini into a straight line by its passing through a migration path having in a portion of it an area not more than several micrometers in diameter, detecting the fluorescence label at both the termini at a predetermined location and measuring the interval between the detection of the fluorescence coming from one terminus and that of the fluorescence from the other or by 2) a DNA molecule bound to a fluorescence label at one terminus and to a particle at the other being led as a whole by such means as electric field application into an aperture smaller in diameter than the particle, leaving the particle fixed at the mouth of the aperture to stretch the DNA molecule and detecting the fluorescence position to measure the distance between the bound particle and the bound fluorescence label.
