Can you get DNA from Fingernails?

Traditionally, the primary source of DNA for genetic study has been blood samples. However, this source’s collection, transportation, and long-term preservation might provide challenges. Here we looked at the possibility of using human nail clippings as a source of DNA for SNP genotyping. A single nail cutting can supply recipient DNA in sufficient amount and quality for the preliminary genotyping needed to identify meaningful molecular markers. Although enough DNA is present in fingernail clippings, the recovery rate is lower, and the DNA is more highly fragmented than when DNA is isolated from peripheral blood. In this blog, we are going […]
