Abstract

Close
- We report on the incorporation of the Visual DNA concept in a genotyping assay as a simple and straightforward detection tool. The principle of trapping streptavidin-coated superparamagnetic beads of micrometer size for visualization of genetic variances is used for PrASE-based detection of a panel of mutations in the severe and common genetic disorder of cystic fibrosis. The method allows a final investigation of genotypes by the naked eye and the output is easily documented using a regular hand-held device with an integrated digital camera. A number of samples were run through the assay, showing rapid and accurate detection using superparamagnetic beads and an off-the-shelf neodymium magnet. The assay emphasizes the power of Visual DNA and demonstrates the potential value of the method in future point-of-care tests.
