Design and efficiency of smarcal1 MOs. (A) Design of smarcal1 MOs and RT-PCR primers for detecting the splice-blocked smarcal1 mRNA. P1 and P2 indicate the primers used in (D). (B) Embryos with injection of smarcal1 5′ UTR-5′cds-GFP mRNA (50 pg per embryo) displayed green fluorescence, whereas co-injection of smarcal1 MO1 (8 ng per embryo) with 5′ UTR-5′cds-GFP mRNA (50 pg per embryo) blocked fluorescence signal. (C) Knockdown efficiency of smarca11 MO1 analyzed by Western blot with V5 antibody. V5-tagged full-length zebrafish smarcal1 injected embryos (200 pg per embryo) showed the induction of 85 KD protein, whereas co-injection with 8 ng of MO1 inhibited the protein translation. A 105 KD non-specific band and β-actin serve as loading control. (D) RT-PCR analysis of splice-blocking efficiency of MO2. A 640 bp product was amplified from WT embryos and MO2 deleted about 70 nucleotides of smarcal1 mRNA. In each group, 20 embryos were pooled for western blot and RT-PCR experiments. |
