    Abstract: The present inventors established ES cell lines in which one of Cds1 (Chk2) alleles was inactivated by using gene targeting. Chimeric mice were constructed using the cell lines, and genetically modified mice in which both of the Cds1 (Chk2) alleles were inactivated were constructed. Furthermore, by incubating the ES cell lines in which one of Cds1 (Chk2) alleles was inactivated in a selection medium containing a high concentration of an antibiotic, the present inventors constructed mouse ES cell lines in which both the alleles were inactivated. The mice and cells established from the mice can be utilized in screenings for compounds that regulate the cell cycle.
