Abstract:
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.

Abstract:
A bioassay method in which the efficiency of an interaction between substances such as hybridization is enhanced by controlling the production of an electric field in a reaction region where the interaction occurs, and a bioassay device for preferably implementing the method are disclosed. The method is conducted to detect an interaction between substances by using a detector (1(10)) at least having a detection surface (S(S')) subjected to a surface treatment for fixing a substance D for detection, a reaction region (R(R')) for providing a field where an interaction between the detection substance D fixed to the detection surface (S(S')) and an added target substance T occurs, and electric field producing means (E) for producing an electric field in the reaction region (R(R')) by causing a potential difference in the reaction region (R(R')). The method comprises a procedure of turning on/off the electric field producing means (E) at a predetermined timing so as to produce/extinguish an electric field.
Abstract:
It is intended to clarify the undisclosed part of the mechanism controlling the circadian rhythm. It is newly found out that RORa (retinoic acid binding-receptor alpha, the same applies hereinafter) promotes the induction of Bmal1 expression and that the induction of Bmal1 expression is promoted under hypoxic conditions. These facts strongly suggest the presence of the mechanism controlling the circadian rhythm wherein, when RORa expression is promoted under hypoxic conditions etc., the induction of Bmal1 expression is promoted and the promotion of the induction of Bmal1 expression promotes the binding of BMAL1 to CLOCK to thereby promote the induction of the expression of the Per gene or the Cry gene. Accordingly, the above findings are likely applicable to agents for regulating jet lag and anticancer drugs.
Abstract:
The object is to increase the S/N ratio in the detection of the occurrence of hybridization to increase the detection accuracy. Disclosed is a hybridization detection method, in which the hybridization between a probe nucleic acid chain with a target nucleic acid chain is allowed to proceed in a reaction system, and then the temperature of the reaction system where the hybridization proceeds is raised to a temperature higher than a predetermined temperature, thereby increasing the S/N ratio in the detection of the hybridization.
