Optimal Activation of Isopsoralen To Prevent Amplicon Carryover

We compared the efficiencies of activation of the photochemical isopsoralen compound 10 and its resulting amplicon neutralizations under conditions with a UV transilluminator box at room temperature (RT) and a HRI-300 UV photothermal reaction chamber at RT and at 5°C. Our data suggest that use of the HRI-300 reaction chamber at 5°C results in a statistically significantly higher degree of amplicon neutralization.
