Open the CIPO recordAbstract From the Canadian patent
There is provided a signal amplification method for detecting a mutated gene, which can increase the detection sensitivity of mutated genes on a DNA chip according to the PALSAR method can establish efficient , signal amplification and can establish simple detection by contriving design of oligonucleotide probes for use in the PALSAR method. The signal amplification method comprises a ligation reaction with a DNA ligase and a self-assembly reaction which forms a double-stranded self-assembly substance having a regular higher-order structure of oligonucleotides wherein the detection sensitivity of the mutated gene on a DNA chip is improved.
