zfAPEX1, expressed throughout development, is a maternal protein. Embryos at different stages were probed by in situ hybridization, using full-length transcript of the zfAPEX1 cDNA. mRNA is found throughout the embryo at all stages, although at later stages it is more heavily expressed in the head region. Note the density of stain in the cardiac region at 48 and 72 hpf.
