The Morpholino antisense oligo against zebrafish smyhc1 was synthesized by Gene Tools (Corvalis, OR). The smyhc1 translation blocker (ATG-MO, Table 1) was designed to target the sequence flanking the ATG start site (32 (link)). The standard control-MO was purchased from Gene Tools. The Morpholino antisense oligos were dissolved with 1× Danieau buffer (39 (link)) to a final concentration of 0.5mM. Zebrafish embryos at the 1 or 2 cell stage were injected with approximately 2 nl (10 ng) of the ATG-MO.
