Abstract

The present invention relates to a multi-hybridization set for DNA microarray assay, which comprises: a lower plate in which a DNA microarray is mounted; an upper plate which is coupled to the lower plate, and in which one or more O-rings are attached to the lower surface of the upper plate coming in contact with the DNA microarray such that separate spaces are formed when the upper and lower plates are coupled to each other, the upper plate having sample injection holes formed inside of the O-ring; and means for coupling the upper and lower plates to each other. The multi-hybridization set of the present invention allows the DNA microarray assay of several samples to be performed at once. In addition, according to this multi-hybridization set, the problem of contamination caused by oil and dust, which occurs due to the use of the existing cover glass, can be solved.

Claims

an upper plate which is coupled to the lower plate, and in which one or more O-rings are attached to the lower surface of the upper plate coming in contact with the DNA microarray such that separate spaces are formed when the upper and lower plates are coupled to each other, the upper plate having sample injection holes formed inside of the O-ring; and

means for coupling the upper and lower plates to each other.

2. The multi-hybridization set of claim 1, wherein bolt or screw grooves (or holes) are formed on the upper surface of the lower plate, and bolt or screw holes are made in the upper plate in such a manner as to correspond to the grooves (or holes) of the lower plate, such that the upper and lower plates can be coupled to each other by means of bolts or screws.

3. The multi-hybridization set of claim 1, wherein a pinhole is made in the upper plate and a pin is inserted into the pinhole, such that the upper and lower plates are easily separated from each other.

4. The multi-hybridization set of claim 1, wherein positioning protrusions are formed on the inner surface of either of the upper or lower plates, and positioning grooves are formed on the inner surface of the other plate in such a manner as to correspond to the positioning protrusions.

5. The multi-hybridization set of claim 1, wherein the number of the O-rings attached to the lower surface of the upper plate is 4 to 16, and the sample injection holes are formed by perforating the upper plate along the inner circumferential edge of each of the O-rings.

6. The multi-hybridization set of claim 1, wherein the number of the O-rings attached to the lower surface of the upper plate is 1 to 8, and a plurality of the sample injection holes are formed at the inside each of the O-rings.
