Student Theses
As the significance of trace DNA has increased over time, it has become more important to optimize each process to avoid any loss of genetic material. Factors that could negatively affect the quality and quantity of DNA during transport or storage include environmental temperature, the DNA collection devices, the packaging, and possible contamination. This study compared the DNA stability of saliva stain swabs collected by moistening the swab with deionized water or Sample Keeper and stored at room temperature. Sample Keeper (Microread Genetics, Beijing) is a proprietary buffer marketed as a DNA stabilizing agent. We swabbed 110 saliva stains from …
