| description | The guide RNAs were injected into zygotes from a cross of (C57BL/6 x CBA)F1 females with Krastm3Bbd/Kras+;Trp53tm1.1Dgk/Trp53tm1.1Dgk males on a mixed 129/Sv-C57BL/6 genetic background. |
| molecularNote | Alanine codon 155 (GCC) in exon 5 was changed to a stop codon (TGA) (p.A155*) using an sgRNA (targeting GGAAGATATGTAATCAGGCTCTT) and an ssODN template with CRISPR/Cas9 technology. |
