Rat floxed alleles generated by zygote electroporation. a Schematic representation of CLICK: CRISPR with lssDNA inducing conditional knockout alleles. b Schematic approach to generate rat Vapb floxed alleles using the CRISPR/Cas system with lssDNA composed of the targeted exon flanked by two loxP sites (Additional file 11: Figure S11). c PCR analysis of rat pups (#1–6) generated by CLICK, showing different types of mutations, indels, LD (via NHEJ), inversions, and floxed alleles (via HDR) (black arrow). The primer sets were used for PCR and sequence analysis (Additional file 2: Figure S2). M: 100 bp DNA ladder marker. d Sequence analysis of 6 pups showing a variety of mutations, indels, inversion or LD indicated by red letters, and loxP insertions and flox indicated by orange letters. All pups were used for testing germline transmission (Additional file 15: Table S1). Asterisks indicate pups used for testing the Cre-loxP system (Additional file 17: Table S3)
