Abstract:
1. A DNA analysis apparatus, comprising: a movable stage supporting a DNA holding carrier which holds a DNA sample; a substrate supplying part which individually supplies plural types of substrates for complementary strand synthesis to the DNA sample held by the DNA holding carrier; a reaction vessel which accommodates a reaction solution that produces luminescence through reaction with a DNA complementary strand synthesis reaction product, wherein the reaction solution contains Apyrase that degrades the substrates; a photodetector disposed proximal to the reaction vessel to detect luminescence produced in the reaction solution; and a computer to control positioning of the stage and control dispensing of the substrates for complementary strand synthesis onto the DNA holding carrier from the substrate supplying part, wherein the computer positions the stage so the DNA holding carrier is spatially separated from the reaction solution in the reaction vessel and the DNA holding carrier receives the substrates from the substrate supplying part for performing complementary strand synthesis, and then moves the stage so that the holding carrier is dipped into the reaction solution in the reaction vessel for performing a luminescence reaction and degrading the substrates by Apyrase.
