Extended Data Figure 2. RNA cleavage is marginally stimulated by di- and trideoxyribonucleotide PAMmers.

Cleavage reactions contained ~1 nM 5′-radiolabelled target ssRNA and no PAMmer (left), 100 nM 18-nt PAMmer (second from left), or 1 mM of the indicated di- or tri-nucleotide (remaining lanes). Reaction products were resolved by 12% denaturing polyacrylamide gel electrophoresis (PAGE) and visualized by phosphorimaging.
