Recombinant Ago2:5'P -pre-miR-24-1 complex is active against a 5'- but not a 3'-arm target. Cleavage assay results of recombinant Ago2 pre-incubated with 5'-P-pre-miR-24-1 before the addition of radiolabeled 5'-arm (Ta-5) or 3'-arm (Ta-3) target. Predicted sizes of 5'-end cleavage products of 5'- and 3'-arm targets are 17nt and 14nt respectively. Radiolabeled pBR322/MspI (M) was used as size marker.
