ALT V. m. juice displaces EtBr, which cannot backwards displace V. m. juice. Tracks on horizontal agarose gels. Wells loaded with 150 μg ctDNA, stained in various ways including V. m. berry juice and destained. – Tracks A1–A6. A single track treated sequentially. A1. EtBr for 9 h 30 min: UV. – A2. EtBr for 9 h 30 min → V. m. juice for 12 h → MQ for 30 min: UV. – A3. EtBr for 9 h 30 min → V. m. juice for 12 h → MQ for 12 h 30 min: Vis. – A4. EtBr for 9 h 30 min → V. m. juice for 12 h → MQ for 15 h 30 min → EtBr for 24 h 15 min: UV. – A5. The same as in A4: Vis. – A6. EtBr for 9 h 30 min → V. m. juice for 12 h → MQ for 15 h 30 min → EtBr for 48 h 15 min: UV. – Tracks B1–B3. A single track treated sequentially. B1. EtBr for 9 h 30 min: UV. – B2. EtBr for 25 h → V. m. juice for 12 h → MQ for 12 h: Vis. – B3. The same as in B2: UV. – Tracks C1–C3. A single track treated sequentially. C1. V. m. juice for 9 h → EtBr for 24 h: UV. – C2. V. m. juice for 9 h → EtBr for 27 h → V. m. juice for 12 h →
