Efficient Morpholino antisense oligonucleotide-mediated knock-down of xirp2a does not affect myofibrillogenesis.
(A) Phenotypically, xirp2a morphants are indistinguishable from WT embryos at 24 hpf. Scale bar: 250 μm. (B) Efficient gene knock-down of xirp2a is assessed by immunohistochemistry at 24 hpf. Green: Xirp2a; red: Actin. Scale bar: 20 μm. (C) Complete loss of Xirp2a does not affect myofibrillogenesis and correct sarcomeric organization of skeletal muscle as determined by immunohistochemistry using an antibody against the A/I junction epitope of Titin and rhodamine phalloidin to label sarcomeric Actin at 24 hpf. Green: Titin; red: Actin. Scale bar: 5 μm.
