Stability of the Armored DNA. (a) Stability of armored DNA in SM buffer. Armored DNA in SM buffer was stable at 4°C for more than 3 months, at 37°C or room temperature was stable for 2 months. The mean for low-copy samples at 4°C was 52,722 copies/ml (4.72 log10; range: 49,239-96,210 copies/ml), and the coefficient of variation was 10.1%. The mean for high-copy samples at 4°C was 5,623,413 copies/ml (6.75 log10; range: 5,510,008-9,575,051 copies/ml), and the coefficient of variation was 6.3%. (b) The stability of armored DNA in plasma. The stability of armored DNA in plasma was poor. The high-copy Armored DNA was not stable for more than 5 days at 4°C, 37°C, or room temperature; the low-copy armored DNA in plasma was not stable for more than 3 days at 4°C, 37°C, or room temperature.
