Design and characterization of the ush2aΔexon30-31 and ush2aΔexon39-40 zebrafish line
(A) Schematic representation of the exon-excision approach. Sanger sequencing confirmed the presence of the anticipated excisions in injected embryos (1 day post fertilization [dpf]). Excision of the genomic region containing ush2a exons 30 and 31 resulted in the insertion of two nucleotides (TT) at the repair junction. (B) RT-PCR analysis revealed the absence of ush2a exons 30 and 31 in ush2aΔexon30-31 larvae and the absence of exons 39 and 40 in ush2aΔexon39-40 larvae (5 dpf). Sanger sequencing of the ush2aΔexon30-31 and ush2aΔexon39-40 amplicons confirmed the absence of the target exons from the transcript.
