It is intended to provide a method whereby DNA can be conveniently and rigidly immobilized on a substrate at such a high density as achieved by the conventional methods and a method of accurately detecting DNA. A substrate activation kit comprising a phosphate buffer (pH6), a solution A (an aqueous solution) of N-hydroxysuccinimide and a solution B (a dioxide solution) of 1-Ä3-(dimethylamino) propyl Ü 3-ethylcarbodiimide; and a method of detecting DNA characterized by comprising spotting DNA on a substrate having been activated by using the above activation kit and then hybridizing the spotted DNA with fluorescence labeled DNA. <IMAGE>
