How much DNA is required to obtain a DNA profile?
• How much DNA is required to do a SNP analysis? There are several ways to run SNP analysis. The required amount of DNA can vary from nanograms to micrograms. A typical SNP analysis requires about 250ng of DNA, but the amount of DNA depends on the assay. Larger punch size or more than one punch per well can provide enough DNA for SNP analysis. • Have long-term stability studies been done with biological material collected on the Buccal DNA Collector™? Yes, ongoing validation of the Buccal DNA Collector has reached 5 years and full DNA profiles are still obtained. The collection paper for this device has been used since 1963 for the collection of biological materials. • Why buccal cells instead of blood? Buccal collection is a non-invasive DNA collection method that eliminates risks associated with handling and transferring blood samples. Collection, processing and storing is significantly less expensive when using buccal cells as well. For additional information on this product, please
