Genomic Loci Enrichment
RainDance Technologies’ platform was designed to enable PCR for high-throughput amplification of targeted regions of the genome, according to James Brayer, manager of commercial scientific applications.
“The RainDance Sequence Enrichment Solution allows researchers to generate targeted resequencing data necessary for the characterization of rare variants associated with human health and disease,” he says.
RainDance launched its first commercial application earlier this year, leveraging the company’s RainStorm™ microdroplet-based technology. “This application facilitates the follow-up of genome-wide association studies and the resequencing of candidate genes and certain pathways of interest,” he notes.
“Because we use PCR, we can target those genome areas that are of interest to researchers—areas that are often inaccessible using alternative enrichment methods due to repetitive sequence or regions of high homology. The droplets produced are uniform, resulting in consistent amplification of the greater than one million droplets generated per sample. Consequently, targeted regions are uniformly represented. The process is scalable.
“Researchers apply this technology to accurately identify rare variants, which is critical to understand the genetic basis of disease. Via collaboration with Expression Analysis, we work with eight researchers in the cancer community, each with a slightly different target in mind, to analyze genome content.”
