A method is presented to measure homologous recombination in mouse embryonic stem cells by both gene targeting and short-tract gene conversion of a double-strand break (DSB). A fluorescence-based reporter is first gene targeted to the Hprt locus in a quantifiable way. A homing endonuclease expression vector is then introduced to generate a DSB, the repair of which is also quantifiable.
