  • ShortCut® RNase III, used with its manganese-containing reaction buffer, converts long double-stranded RNA into a heterogeneous mix of short (18–25 bp) interfering RNAs (siRNA) suitable for RNA interference in mammalian cells (1–3). 1.5 units (1 µl) of ShortCut RNase III is sufficient to convert 1 µg of dsRNA into siRNA suitable for RNA interference in mammalian cells.

    ShortCut RNase III digestion of dsRNA: (A) Varying amounts of ShortCut RNase III were incubated with 2 µg of a 500 bp dsRNA for 20 minutes at 37°C in a 50 µl reaction. Digests were analyzed by 20% TBE polyacrylamide electrophoresis. Marker lane contains a mixture of 21 bp siRNA Marker and 100 bp DNA Ladder (NEB #N3231). (B) dsRNA fragments (1 kb and 175 bp) were digested with ShortCut RNase III. Digests were analyzed by 20% TBE polyacrylamide gel electrophoresis.
    GFP Silencing in COS-7 Cells: COS-7 cells co-transfected in a 24 well plate with a plasmid expressing GFP in the absence (control) or the presence of 30 ng (4 nM) of GFP siRNA prepared using the ShortCut RNAi Kit. Cells were photographed 48 hours post-transfection.
