Plastic surface treated with PHMG-Cl inactivates eDNA. Shown here is a 1.2% agarose-TA gel stained with EtBr to visualize eDNA recovered from plastic treated with PHMG-Cl for up to 28 days. PHMG-Cl treatments (1%, 0.5%, 0.1%, and 0.05% are grouped according to the length of exposure (days). Treatments: (1) clean-surface control, (2, 6, 10, 14, 18, 22, and 26) 1% PHMG-Cl, (3, 7, 11, 15, 19, 23, and 27) 0.5% PHMG-Cl, (4, 8, 12, 16, 20, 24, and 28) 0.1% PHMG-Cl, and (5, 9, 13, 17, 21, 25, and 29) 0.05% PHMG-Cl.
