Expression of β2 subunit transcript variants in the embryo and adult. RT-PCR analysis using transcript variant-specific primers (located in the 5' exons 1 or 2 and exon 10) was performed on RNA samples from A) whole embryos at various developmental stages, B) cardiac tissue dissected from cmlc2:GFP embryos or from adult fish, and C) adult organs and tissues. Expression of a housekeeping gene, EF1α, was used as a control for RNA integrity. In B, 72 hpf or adult RNA reactions were run on single gels, subsequently subdivided to multiple panels for clarity in presentation. Transcript variant numbers are listed to the right of panels; refer to Fig. 1D.
