(A–A”) Confocal images of a 48 hpf host embryo injected with H2B-mCherry mRNA (magenta) and transplanted with Tg(sox17:GFP) expressing donor endoderm showing the chimeric islet (yellow arrowhead). (B) High-resolution melt analysis patterns for genotyping ins +/+ (blue), ins +/- (green) and ins -/- (brown) animals. (C) Representative example of genotyping 31 chimeric adults, revealing 8 of 31 animals to be mutant (brown). Scale bar: 200 μm.
