Interaction test equipment biomolecular interaction test method of biomolecules, the melting temperature measuring method for biomolecular array method for detecting nucleic acids

摘要

PPROBLEM TO BE SOLVED: To provide a means capable of rapidly forming an interaction between bio-molecules without requiring many samples or much time and manpower and capable of detecting the interaction between the bio-molecules on a real time basis. PSOLUTION: This interaction testing device of the bio-molecules comprises a bio-molecule micro array 1 where bio-molecules are fixed onto a substrate, and a transparent electrode 2 disposed so as to be faced to the surface to which the bio-molecules of the micro array are fixed. The device has a non-conductive spacer 3 between the micro array 1 and a counter electrode 2, and a cavity 4 is formed of the micro array 1, the spacer 3, and the counter electrode 2. The micro array 1 has a conductive material surface 6 in at least a part of the bio-molecule fixed surface, and two through holes 5 leading to the cavity 4. One through hole is used for injecting solution to the cavity, and the other through hole is used for discharging the solution from the cavity. PCOPYRIGHT: (C)2006,JPO&NCIPI
