Figure 3.
Non-injected and microinjected zygote blastocyst development rates and mutation and deletion efficiencies following microinjection of Cas9 protein and either in vitro transcribed (IVT) or synthetic gRNAs btHP 5′g2 and btHP 3′g2 at 6 h post insemination. (a) Blastocyst development rate of microinjected and non-injected control embryos (green). (b) Mutation rates and (c) deletion rates in embryos injected with Cas9 protein, btHP 5′g2 and btHP 3′g2. A blastocyst was considered mutated if a mutation was detected at one or both target sites. (d) Frequency of types of deletions detected in microinjected embryos. Mono = monoallelic (orange); Bi = biallelic (aqua), Mosaic (purple). Error bars = SEM. **P < 0.01; ***P < 0.001.
