Description
Tp53tm1/Bcgen rats are a useful model for studying tumor formation, screening in vivo carcinogenicity, and examining the efficacy of therapeutic agents.
The Tp53 KO rat model was developed using targeted TALEN technology in the Sprague-Dawley strain. This model possesses a 12 bp deletion and 2 bp insertion within Exon 2 of Tp53 on chromosome 10. This strain was maintained by mating heterozygous females with homozygous males on a Sprague-Dawley genetic background.
