Validation of the presence of col6a1 mRNA by RT-PCR at different developmental stages in different organs of zebrafish.
(A) Confirmation of the presence of col6a1 mRNA in different organs of adult WT zebrafish: col6a1 mRNA is detected in the electrophoregram of organs from adult fish as indicated at the top of the panel. β-actin is used as internal control. (B) Confirmation of the presence of two forms of col6a1 mRNA in wild-type (WT) and mutant (presenting exon 14 skipping) zebrafish embryos at 2 dpf from col6a1ama605003 line. WT fish express only the wild type allele (298 bp); heterozyogous mutant (HT) carry both wild type and mutated allele (244 bp) and homozygous fish (HM) express only the exon-skipped form.
