Fig. 1From: Efficient generation of GGTA1-null Diannan miniature pigs using TALENs combined with somatic cell nuclear transferSchematic of TALENs targeting the porcine GGTA1 locus and the activity assay. a Schematic diagram of pig GGTA1 partial protein coding region and the TALENs targeting loci. The red arrow indicates the target site of the TALENs on the exon. b The SSA recombination assay was used to determine the targeting efficiency of the TALEN vector in vitro (*P <0.05)Back to article page
