PURPOSE:To provide a method for detecting nucleic acid which is easy, safe, reliable and simple. CONSTITUTION:A solid carrier suspected to attach or contain nucleic acid is brought into contact with a polyamine to which a label (or its precursor) capable of giving measurable signals is bound, forming a composite made up of the nucleic acid and the polyamine. In case the precursor is used, it is transformed into the label. Before and after the transformation, the residual polyamine not forming the above composite is eliminated and then the label is probed, thus detecting the nucleic acid. |
