Abstract

The substrate 100 for use in the analysis of a nucleic acid according to the present invention has multiple analysis areas 12 which are partitioned on a substrate 10 , and enables the measurement of the analysis areas 12 while interchanging the analysis areas 12 in turn, said substrate 100 being characterized in that each of the analysis areas 12 consists of an adsorption part 13 onto which a DNA fragment or a carrier having the DNA fragment carried thereon can be adsorbed and a non-adsorption part 14 which is a part outside of the adsorption part 13 , and the non-adsorption part 14 has, formed on at least a part thereof, a marker part 15 that has a specified shape and helps to identify the positions of the analysis areas 12.

First claim

The invention claimed is:

1. A nucleic acid analysis device comprising:
a flow cell for use in analysis of nucleic acid having a substrate,
the substrate having a plurality of analysis areas partitioned on the substrate,
each of the analysis areas having a plurality of absorbent portions capable of absorbing a DNA fragment or a vector where the DNA fragment is borne,
at least one of the analysis areas having the plurality of absorbent portions and a non-absorbent portion other than the absorbent portions, and at least a part of the non-absorbent portion defines a first marker portion having a predetermined shape disposed at a center of the respective analysis area and plural second marker portions each having respective predetermined shapes and disposed at corners of the respective analysis area;

a piping connected to the flow cell to pass a fluid through a flow passage of the flow cell;
a temperature control device that controls a reactive temperature of the flow cell;
a light source that irradiates excitation light onto the at least one of the analysis areas serving as an analysis target;
a detection unit including a detector that detects fluorescence emitted from the analysis target by irradiating the excitation light thereon; and
a stage configured to support the flow cell and a driving motor configured to move the stage,
wherein, in each of the at least one of the analysis areas, straight lines obtained by linking the respective second marker portions are separated from the respective first marker portion by a same distance.

2. The nucleic acid analysis device according to claim 1 , wherein the driving motor is configured to move the stage in each of X-axis and Y-axis directions which are coplanarly perpendicular to each other.
