DNA templates for in vitro transcription were characterized following synthesis. A, I-PpoI digestion of DNA templates for in vitro transcription. Lane M, New England Biolabs 50-bp DNA ladder labeled with [32P]phosphate; lane 1, I-PpoI digestion of unmodified control DNA template; lane 2, I-PpoI digestion of B[a]P-N6-dA-modified DNA template. B, BsiWI digestion of DNA templates for in vitro transcription. Lane M, IDT 20/100 DNA ladder labeled with [32P]phosphate; lane 1, BsiWI digestion of unmodified control DNA template; lane 2, BsiWI digestion of B[a]P-N6-dA-modified DNA template.
