You can't trace the disease genes, but you can trace the marker to them. Detecting SNPs can help in disease diagnosis, therapy and prevention, Walkovich said. So pharmaceutical companies are really excited about these SNPs. Walkovich and Smith worked on the development of an easy, simple and consistent procedure to detect SNPs. First, they used a special assay to mark a specific SNP with a florescent marker.
Chips are small separation devices.
It can rapidly load the reaction products from the SNP reaction and basically it can genotype the SNP type. The chips can separate large sample mixtures of DNA quickly and efficiently, Price said. But the significance is certainly it's somewhat of a novel approach at scaling out the detection.
