Fig. 6. RT-PCR analysis of various tissue specific genes in control and embryos
injected with HpTb morpholino. Total RNA was isolated from 50 control
embryos and 50 embryos injected with HpTb morpholino antisense
oligonucleotides at 28 hours after fertilization. Southern blotting of RT-PCR
products. (-) and (+) indicate uninjected and injected embryos. The genes
analysed are discussed in the text.
