The supernatants were removed via pipet, and the resin washed with phosphate buffer (3 × 50 μL). Photolyses were carried out in eppendorf tubes containing phosphate buffer using a transilluminator as described in reference 5. The supernatant was removed and analyzed by Cerenkov counting and/or nondenaturing polyacrylamide gel electrophoresis.
