摘要:
Disclosed herein is a method and apparatus for determining the base sequence of a nucleic acid molecule by cleaving a nucleic acid molecule of interest while controlling the cleavage site, measuring the change in mass which occurs in the nucleic acid molecule after the cleavage step, and acquiring the base information of the cleaved nucleic acid molecule from the data about the change in mass. The method and apparatus are based on the principle which is entirely different from that used for the conventional technique.

摘要:
A circadian rhythm control gee cluster (Bmal1 gene, Npas2 gene, Rev-erbα, Dbp gene, Per3 gene, Per2 gene and Per1 gene) having a given expression timing and expression sequence under normal conditions is provided along with a DNA chip having, at least, the circadian control gene group sequentially arranged. There are also provided a method for predicting modulation in expression timing of the circadian rhythm control gene cluster, a method for detecting a circadian rhythm modulation, a method for selecting a circadian rhythm regulator, a method for screening a circadian rhythm regulator, and screening of a substance involving modulation of a circadian rhythm as a side effect, each using the DNA chip.
摘要:
An object of the present invention is to clarify unelucidated aspects in the control mechanism of circadian rhythms. The present inventors have newly found that RORα (retinoic acid binding-receptor alpha; the same shall apply hereinafter) stimulates an induction of Bmal1 expression and also that the induction of Bmal1 expression is promoted under hypoxia. These findings strongly suggest the existence of a control mechanism of circadian rhythms that, when RORα expression is promoted under hypoxia or the like, an induction of Bmal1 expression is stimulated and, when the induction of Bmal1 expression is stimulated, binding between BMAL1 and CLOCK is stimulated and an induction of Per gene or Cry gene expression is stimulated. The present invention, therefore, has applicability as jet-lag regulating agents and anticancer agents.
摘要:
Disclosed is a bioassay method in which, by controlling the electric field formation in the reaction region where an interaction between substances, such as a hybridization, is performed, the efficiency of the interaction can be improved. Also disclosed is a bioassay apparatus in which the method can be favorably carried out. The method includes at least a step of turning on/off the electric field formation by the electric field-forming means E at a predetermined timing.

摘要:
The present invention provides a hybridization detector (1a) and the like that are improved in the hybridization efficiency by arraying nucleotide probes in a stretched form, a sensor chip including the hybridization detector (1a) or the like, and a method of hybridization using these detectors or the chip. The hybridization detector (la) and the like include a reaction region (R) for hybridization between the nucleotide probes (X) and target nucleotide sequences (Y) having a base sequence complementary to the nucleotide probes (X). The reaction region (R) has a configuration for stretching the nucleotide probes (X) by an electric field and immobilizing the nucleotide probes (X) on ends (E) of scanning electrodes (C) by dielectrophoresis.

Disclosed is a bioassay method in which, by controlling the electric field formation in the reaction region where an interaction between substances, such as a hybridization, is performed, the efficiency of the interaction can be improved. Also disclosed is a bioassay apparatus in which the method can be favorably carried out. In the method, an interaction between substances is detected by a detecting element 1 (10), the detecting element including at least a detection surface S (S′) which is surface-treated for immobilizing a detecting substance D, a reaction region R (R′) which provides a field for interaction between the detecting substance D immobilized on the detection surface S (S′) and a target substance T, and an electric field-forming means E which forms an electric field in the reaction region R (R′) by applying a potential difference in the reaction region R (R′), and the method includes at least a step of turning on/off the electric field formation by the electric field-forming means E at a predetermined timing.

An imaging apparatus includes a pixel unit, an amplifying transistor, and a control unit. The pixel unit includes a first photoelectric conversion unit generating a first charge based on incident light of a first color, a second photoelectric conversion unit generating a second charge based on incident light of the first color, and a third photoelectric conversion unit generating a third charge based on incident light of a second color. The amplifying transistor is provided in common to the first to third photoelectric conversion units, and outputs a signal based on the first, second, and third charges generated by the first, second, and third photoelectric conversion units, respectively. The control unit sets the pixel unit to a selected state or a non-selected state according to an electric potential of a control terminal of the amplifying transistor.
