Abstract:
We have focused on DNA strand exchange reaction (SER) with partially double-stranded (PDS) probes as a novel platform of SNPs genotyping. In this report, we elaborated the method for reliable and high-throughput SNPs typing. Competitive reactions using a couple of PDS probes designed for wild and mutant sequences significantly increase resolution efficiency to SNP types that is hardly discriminated by a non-competitive reaction with a single probe. Integration of the PDS probes with DNA microarray technology enable us to increase throughput efficacy. Simple and quick typing of fifteen SNPs with reliability as high as a ligase-based assay was demonstrated.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
