General accelerated aging theory
QIAsafe DNA Blood Tubes and 48-Well Plates provide innovative QIAsafe matrix technology for dry storage of 50–200 μl blood samples at room temperature without degradation of DNA. The rate of a chemical reaction increases with temperature.
A conservative generalization based on the Arrhenius equation states that reaction rates double with every 10°C increase in temperature. For example, a sample left at ambient room temperature (15–25°C) for 5 years would have the same level of degradation as a sample placed at 50°C for 37.5 weeks. The application of the Arrhenius equation enables different industries to accurately accelerate product aging and support their shelf life claims.
Refrigeration costs are eliminated, and samples can be conveniently archived or shipped at ambient temperatures. Blood samples are easily recovered by simple rehydration and can then be used straightaway in DNA purification protocols. Accelerated aging studies: A temperature increase of 10°C corresponds to a twofold increase in shelf life. For example, DNA stored at 40°C for 2 years corresponds to an estimated storage time of 8 years at 20°C.
