From: The effect of silica desiccation under different storage conditions on filter-immobilized environmental DNA

Fig. 2

Relatively abundant eDNA is better preserved on filters desiccated with silica rather than immersed in ethanol (EtOH) at warmer temperature. Transformed cycle threshold (“Transformed Ct”) values of IntegritE-DNA™ qPCR tests targeting chloroplast DNA isolated from filters preserved by EtOH submersion and silica desiccation (n = 2–3) at the indicated temperatures and time periods. Ct values were transformed by subtracting the value from 50.001 for more intuitive visualization of the change in DNA quality over time. A clear decrease in DNA quality is observed in the 23 °C EtOH-stored filters. The data are plotted as medians with median absolute deviations (error bars)
