Agarose gel analysis of the RT-PCR products showed exon-23 and exon-22/23 dual skipping in mdx mouse myotubes in vitro. Concentrations of AOs used include 2.5 nM, 5 nM, and 12.5 nM. (A) Fully modified 2′-OMe-PS control AO; the original gel image is shown in Fig. S2(A2) (Supplementary Information). (B) 2′-OMe modified 2′-F-PS AO chimeras including 2′-OMe/2′-F-PS gapmer, 2′-OMe/2′-F-PS mixmer 1, and 2′-OMe/2′-F-PS mixmer 2; the original gel image is shown in Fig. S2(B2) (Supplementary Information). (C) LNA modified 2′-F-PS AO chimeras including LNA/2′-F-PS gapmer, LNA/2′-F-PS mixmer 1, and LNA/2′-F-PS mixmer 2; the original gel image is shown in Fig. S2(C2) (Supplementary Information). The corresponding densitometry data of the gel images are shown in Fig. S2(A1,B1,C1) (Supplementary Information).
