Figure 1.

Effects of unc-45b knockdown on thick and thin filament organization in skeletal muscles of zebrafish embryos. A, B. Anti-MyHC antibody (F59) staining shows the organization of thick filaments in trunk slow muscles of uninjected control (B), or unc-45b knockdown (A) embryos at 30 hpf. C, D. Anti-α-actin antibody staining shows the organization of thin filaments in trunk muscles of uninjected control (D) or unc-45b knockdown (C) embryos at 30 hpf. Scale bar = 25 μm in A, B, C, D.
